Will check the o2 sensor but from a glance it appear to be fine.

Stock intake.

When I have a chance I will change out the plugs and unbolt the high flow cat and run it with an open downpipe to see if there is any difference.

Would a clogged cat cause it not to idle? I am still thinking I may have a vac leak.

Thanks all for the suggestions.

 

bumpity

I changed out all the plugs and no difference. Still havent had a chance to run open downpipe and still will check the o2 sensor.

ReTed, Aaroncake, Icemark, Evil Aviator!

 

Just came back from unbolting the cat and tried running it and still the same.

Running an open downpipe is louder than the voice of god.

o2 sensor wire was fine.

I am running out of things to look for... I am getting desperate.

How can I check for vac leaks if I cant get my car to idle?

 

O2 sensor wouldnt have anything to do with idle anyway. It just feeds the ECU a signal during constant speed driving and runs in open loop mode to save a little fuel..
Can you hold the gas down and let it "idle" at around 2000 RPM? If so do this, or have a friend do it and check for vac leaks then. If you are *sure* that there are no vac leaks..Id go for a compression check after that..

 

Yea I figured the o2 sensor did not have to do with the car not idling.

Yes I can hold down the gas "making" it idle. Would a better idea be to tighten the throttle cable since it would be more constat than say an unsteady foot?

 

Have you tried to adjust your TPS? Maybe it's not working properly.. .. have you had the chance to test it?

 

Check all TID connections and intake areas, any intake leaks will cause big problems. And test your compression/pray.

Check or Fast Idle cam screw, Might have came loose not alowing any air into intake?

 

I'll look up the fast idle cam screw in the FSM.

Bump! ReTed I see you are online please offer some insight!

 

well I fixed whatever the problem was, still not too sure what it was though.

Here is the cliffnotes version:
-checked all hoses and plugs
-changed spark plugs
-ran it with open downpipe
*at this point car would not idle

Fast forward to today
-but high flow cat back on
-wedged a piece of cardboard so the throttle cable was holding the idle at 1500 rpm
-began spraying carb cleaner around to look for vac leaks but no changes in idle while spraying around hoses and such
-checked the cat and saw it was glowing slightly by the time it reached operating temp
-removed cardboard wedge and car idled itself

The car runs fine now except it will not hold an idle until operating temps have been reached and also slow to build boost because of the clogged cat.

What I think happened was that running the car with open downpipe cleared up all the buildup from the clogged cat. Not to sure but that is what I am guessing.

Thanks to all those that helped me out.

 

What do you mean can't hold idle until operating temp? Does the idle bounce or does it die?

 

just stalls. I think I need to check my TPS though.

Do you still have the turbo back? I wont be running my car around with a clogged cat.

 

I had that problem before the thermowax was replaced, heck, it was only one week old. Double check it.

Turbo back is gone, I returned it.

I just sold my extra RB turbo back this weekend too, bad timing.
