when you chaps have finally finished hijackin the shit out of my thread i'll announce what pocvips is! :)

drum roll please..........

After much ado im proud to announce pocvips is...

Pauls
Obvious
Cure for
V6
Idle
Problem
Sorted!

Yep its cured! pah! i laugh at pocmuc (whatever it is!!!) :)

Heres the score,up to now we (tony and i) have looked down every avenue to find out why these v6's are sometimes closing the ISC during warmup...i reckon i nailed it down to the alternator charge rate dropping below 13v at idle which was having a direct controlling affect on the idle speed.Quite why this is happening on swaps and not in camrys we havent got a clue.....theres clearly more going on inside the ECU than we can ever work out,so ive basically had enough of this problem and decided to tackle it from a woods perspective....im not happy with opening idle bump stops (this moves the TPS as well) or adjusting timing to 17* as thats too much advance in my book so a simple and effective solution needed finding.....pocvips!

so here it is v6 boyos,quite simply its a waste of time trying to figure out why the ISC is being closed occassionally during warmup,we've been trying for ages now and failed.So the answer is simply to STOP the ISC from closing.

I spoke to tony about this one night on the phone and from there it was decided this would be the simplest,most hassle free way to cure the problem.The ECU and alternator or both! can do what they please,as long as we manually hold the ISC open at 900rpm but still give the ECU control to open it further if it likes then thats the solution.

Stage one of pocvips was getting a v6 to idle naturally at 900rpm,then i unplugged the multiplug going to it,that freezes the valve in its last position which was 900rpm.

I then removed the valve and measured how far the plunger was sticking out of the bottom of it.As luck would have it the base of the plunger sits absolutely flush with the base of the ISC for 900rpm.
http://www.twobrutal.co.uk/forum/images/recovered/2006/12/134.jpg

Heres where the woods fix comes in,out with the welder! my cure for everthing! All we need is a small blob of weld on the side of the ISC plunger,this will still let it wind out for coldstart high rpm but will prevent it closing any further than the 900rpm mark.

http://www.twobrutal.co.uk/forum/images/recovered/2006/12/135.jpg

you can just see the small blob on the side of the plunger,careful grinding of the weld got it just right so that the base of the plunger was flush with the ISC body,which we know produces a guaranteed 900rpm of air bypass.

Job well n truly funkin sorted! :thumbsup:

so far during tests the engine has not once been allowed to idle less than 900rpm....and it still has 1500rpm coldstart.

Sometimes you need to think around the problem rather than actually cure it.

If anyone wants their ISC valves pocvipping,i can do them on an exchange basis,i got spares here...so its as simple as sending me your old one when i send the pocvipped one.This is a free service to all TB big members and of course my previous customers.Non big members will need to pay £10 plus postage for an exchange pocvipped ISC valve,or i'll accept a non microwaved take that album in part ex :)

Nice one! Good, logical and practical thinking there Paul... (edit...sorry, You guys... sorry Tony ;) ) - and thankfully just before I was about to fiddle with my throttle stop. :thumbsup: :D

Now all I need to do is figure out why sometimes it idles high - probably need to ground that a/c wire I think.

Just a quicky though - what normally stops the idle valve at the end of the range, and is it going to cause any issues being "stopped" prematurely? Probably not if it simply winds closed under its own devices...? :idea:

So - where do we sign up for the "can you send me one" list? :rofl:

in retrospect:

Paul Obviously Completely Vapourised Idle Problems Sensibly!

Paul Woods

30-12-2006, 12:03

cheers chaps,simple but effective.....fizzy there wont be any problems with the ECU trying to close the ISC during warmup.Basically we arent letting it get past 900rpm so they wont even be allowed to sometimes idle at 500rpm like ive noticed they occassionally do.

So a blob of weld ground down is all it took,i still think the actual problem is the alternator charge rate dropping low at low rpm which is closing the ISC from the power feed side,its been noted that when theres 14.5v at idle the engine never stalls warm or cold.

Who cares though,its fixed.

I'll be offering the pocvipping service to big members in the new year.

I assume that this also stops the part warm stalling problems?

Paul Woods

I can pocvip a valve anytime you like,all i need is for you to send me your complete ISC valve (two bolts hold it on and a few pipes/wires) and i will send you a modified one straight back,instant turnaround! Its a free service cos your a big member,all i ask is you pay the postage.

Cheers for that Paul! In that case then I'll have to wait until I at least get the other car on the road so I have something to runabout it while I wait for the modded one. Is there any sealent/gasket required when refitting it?

If Owen would be kind enough to visit me on the weekend we could get my engine out of the trailer and onto a board on the engine stand I will be able to access the ISC Valve on mine, I could then send mine up to Paul and get it returned to you and when its tried and tested on your car you could send yours to Paul and get it returned to me.

Why, thank you sir! Looks like I'm going to get the pug sorted out and hopefully remot'd by the weekend however. Not too much of a worry then that the mr2 will be off the road for a few days.

23-04-2008, 22:33

Well, I've had an odd one with this. A while ago I bought a refurbished ICV off ebay, and sent it to Paul for pocvip'ing.

With the old unit, it would usually tick over at 500-600 rpm and have a tendancy to stall when in semi-warm state when pulling up at junctions etc.

Anyhow, fitted the modded unit - and it's fine when warming up, tends to tick over at 1000 or so, but once the engine is warmed up the car idles high - 1500-1700 rpm. :eek2:

Took it off and put the old one back on, and left it at that.

Anyhow, as I'm back to using it as my daily driver, decided to try and sort it. Refitted the modded one and had the same problems.

Took the modded icv off and took some time stripping both units and comparing the contents to make sure all seals were intact, bearings were ok, everything worked as expected etc. Also did a resistance check on the pins (as detailed in the haynes manual) and it all checked out. I could not see anything wrong with the new unit, nothing was jammed etc. It fact as part of the refurb it appears to have had new bearings, seals and spring.

As Paul mentioned earlier on here, he has found that the idle stop position of the valve is for the tip of the shaft to be level with the surface - which is as mine is.

I compared the distance the non modded valve protrudes, and filed the weld on the modded icv so it was about a 3rd of that distance out. Quick refit - and now once warmed up its idling at 1100. I didn't want to take too much off on my first try.

Logically this makes sense :idea: - I need the revs to be halfway between what the non-modded and modded valves are idleing at, so the shaft needs to be half way between. So I'll try taking a little more off tomorrow to see if I can get to the ideal 900 mark.

I'm sorta confused as to why this is happening. There's no leaks in the pipes (as I get the idleing low issue on the old icv) and the new one appears sound - in fact the only place that excess air may be getting in is the hole the icv fits into in the first place. I have already tried using blu gasket sealant (as well as the metal gasket) just in case but that made no difference.

If taking a little more off the weld sorts the issue anyway thats great - but just wondering what may be causing me this issue when everybody else appears to have been fine with Paul's std pocvip'd settings? :confused:

I may try putting the pocvip'd shaft into the old icv's housing to see if there's something amiss there, if I have time to tinker tomorrow.

Anybody had any similar issues, or any suggestions as what else I may need to check?

(p.s. - reduced the size of the pictures of the valve in previous post. :rofl: )

Paul Woods

24-04-2008, 06:48

Fizzy

24-04-2008, 12:57

the only logical explanation is that theres a slight air leak somewhere on the throttle body assembly.... with your old valve thats unmodified the ecu is controlling the idle,so even with an air leak its throttling back the ISCV to maintain 800rpm or so,but obviously you have the warm up stall prob.

The modified valve is allowing a bare minimum of 900rpm ish of bypass air around the throttle PLUS whatever air leak you may have,hence why filing down the weld is having an effect.... thats all i can think of.

I take it your throttle bump stop isnt holding the throttle open slightly or anything silly like that?

Checked the throttle bump stop - its not been adjusted at all, and the cable is slightly slack as expected so not holding the throttle open.

Also, with the unmodded one it tended to idle around 500-600 when warmed up - which is below normal/similar symptoms to others which would imply there is no air leak? (I think)

As I said though - a bit baffled. :confused: Perhaps in the refurb of the icv is been skimmed or the opening messed with a bit which is letting in more air - or its off a 3.4 or other model. Who knows...:shrug:

edit: if I do manage to get the new icv to idle at 900 as required with a bit more filing, would there be any issues if there was a slight air leak somewhere?

Fizzy

24-04-2008, 21:14

Well, took the modded valve off again, gave it a very thorough inspection, and filed a little more off the weld.

The car now idles just under 1k - the top edge of the needle is just touching the bottom of the major line for 1k - whatever that actually equates to on a turbo rev counter with the V6. ;)

I do notice that when I push in the clutch while cruising the revs drop to around 1.4k ish, pause for a second, then drops down smoothly to the idle level. Used to do this with the old valve too, so I'm guessing its an autobox related "feature" of the ecu?

I've checked the various pipes for leaks, even pulled off the pipe to the vacume valve which seems to be some sort of choke, as it pushed the throttle open a bit and raises the revs? (even with the hole the pipe was on covered). Its the valve just below the throttle position sensor. Whats this actually used for and when? :confused:

Anyhow, the car seems to finally be a lot happier idleing, and no noticeable drop in light brightness, hum from the power steering/fuel pump or voltage meter which I was having before as the revs where going so low.

So for some strange reason on mine I had to mod pauls mod to get it to idle at desired level. odd.

Paul Woods

25-04-2008, 06:49

the only explanation must be that new ISCV from the states must be flowing more bypass air than a UK camry one,thats all i can think of.

Take the throttle off and check the butterfly in seating all the way around the body. I've had MZ's and VZ's both with bent blades cause this issue. Stepper idle control is a bastard get right without ECU M-REL hold power functionality for ISV post key off reset.

Also check the secondary injector aeration chambers in the lower manifold as these have a BIG effect on idle rpm.

Take the throttle off and check the butterfly in seating all the way around the body. I've had MZ's and VZ's both with bent blades cause this issue.

Well, when the old valve is fitted it idles low - which would imply there isn't an air leak through the ICV, as otherwise it would idle higher (in theory I think anyway).

Stepper idle control is a bastard get right without ECU M-REL hold power functionality for ISV post key off reset.

Erm... not that much into the technical side of things. Can you explain in laymans terms? ;)

Also check the secondary injector aeration chambers in the lower manifold as these have a BIG effect on idle rpm.

Again, old valve caused the engine to idle at 500-600 rpm with the engine was kinda struggling at tickover, causing charging voltage to drop, lights to dim etc. Only thing that has been changed is the icv for the modded one when I encountered this issue - so I don't think its likely to be anything else other than an issue with the new icv itself, or at least thats all I can logically summise..

Been on a few runs now, and idle tends to vary a little (not rapidly/as I watch though ;) ) between the last minor bar and the 1st major bar (the 1k line) which I assume would be down to variation in air temp and pressure on a fixed sized opening. At least its no longer suffering from the staling issue which was the objective anyway. :thumbsup:

this is an observation we made years ago fizz,the ISCV is supplied with alternator voltage on two of its pins,if you have a slightly low idle then the charging rate can dip,and that reduces the voltage to the ISCV power side (should be constant and the valve controlled on the earthing side by the ecu) as a result the valve gets artificially closed some more,which results in lower alt voltage again.... we believe this had a lot to do with the stall problem that we cured in the early days,but quite why it doesnt do that when in the camry remains a mystery.Still its cured with the pocvip mod.

I cant see it being a problem on the throttle butterfly or engine because you would get the same symptoms with BOTH iscv's fitted... the only thing thats being changed is the ISCV itself,so thats got to be flowing more bypass air than the old valve for some reason.

Another stupid question but are the part numbers the same on both of them?

Well, on the old one its a bit unreadable as it was thoroughly cleaned and degreased etc during the biuld. (Jon did a good job ;) ), but what I can see the 2nd half of the part number match.

The new one is something like 22220-68020. I wrote it down but put the paper in a safe place... :banghead:

the old one should be 22270-62020, 22220-68020 is coming up as not applicable for european and jap spec cars,so perhaps owen is right and US spec ISCV's are different and flow more.

Well, found the piece of paper I had written down the number on and its 22270-62020 - which appears to be the correct part number after all. :confused:

Will possibly try getting my original one up for pocvip'ing, and see how I get on with that one. :thumbsup:

Hi Paul,
Is the ISCV pluger stainless? I'll need to buy some rod so I can tig a blob onto mine. I've got some ally lying around though, would be good if it's that, but I kinda doubt it.

It looks stainless yes, can't you just blob a mig weld on it?

Bev

Would if I had one. Went the whole shabang when I bought my first welder and got an ac/dc tig. Glad I did though. Then again, a mig is on the to buy list for pannel work.

Not to dig this up, but i was thinking of sending you a IAC because on my way to work i was having these same symptoms. I read somewhere else that it could be the mr2 power steering drawing on the 80 amp v6 alt that i have lowering it enough to start closing the IAC. So i pulled over because traffic was making juggling the throttle difficult and i unplugged the power to the P/S system and turned the car back on and it idled fine at 700-800. I feel there is some truth to this electrical assumption.

It happens on NON PS cars as well.

Fizzy

....and on my car that was having stalling issues with a stock ICV, changing the jumpers in the ecu completely cured the idle and stalling issues - so it may not just be an electrical issue.

Hmm wierd this morning it started to have the issue again, Thats strange i wonder why just pulling the PS let it idle all the way home but the next day it back to normal? I dont understand. Oh well i will look up what jumpers maybe before i park the car and wait for postage.
