car wont idle... please help

[tlee_20]

ok after installing a new trick flow street heat intake and one inch spacer it wont idle after warm-up. if its cold, it will idle fine. when i take it down the road and it warms up, wont idle at all. stalls when i am driving. dies when i push in the clutch. i have to feather the throttle all the time to keep it running. where should i start?

Im not that great with mustangs yet but sounds to me like a vac leak...

if it were that wouldnt it do it all the time. it only does this after heating up to normal temperature

ok well i adjusted the idle and it seems to be doing ok. still died a time or two but its not doing it everytime i crank the car. if anyone might now whats wrong please let me know. i just want to drive the damn thing.

so no one has any input on this? well i got it to idle finally. it only dies when i turn the wheel. like its putting a load on the engine and kills it. any advice will help....

Was the idle reset? You might need to tweak it to get it to idle right. Here's some info on doing so.

I highly recommend that you put an index mark on the adjusters and take notes on every adjustment you make - that way you can go back to how you have it now if you need to. Otherwise it's easy to end up not knowing where you are in the scheme of overall adjustment.

Good luck.

What cam are you running. Injected 5.0's don't like overlap at all. I made the mistake of trying to run a B-303 cam a number of years ago and I just couldn't keep the car idling. I went to a Crane 2031 and had no problems.
FWIW - I switched over from a Cobra intake to TFS unit and actually had to turn my idle DOWN! It was around 1100 RPM and I now have it set to 750 RPM./

how is your timing looking? timing affects idle speed as well

i figured out the problem. there was an intake leak between my spacer and lower intake. i took the upper off and looked at the gasket. it was leaking in the very middle. what happened i borrowed a friends tfs lower intake because i just had an upper and the middle 2 holes were stripped. when i took it apart i ran the bolts down and they just kept turning. so now i am just gonna buy a new intake. thanks guys

Told you there was a leak somewhere... lol

 

[tlee_20]

yup.. lol. i really didnt think about it being the intake though. the gaskets that came with my spacer were VERY thick. so i figured they'd seal well.. NOT! heh. i guess its part of it. especially not knowing if the lower is junk. thanks guys for your thoughts
