try cleaning your IACV maybe

 

Much respect 'airjordan', but during warm-up, both the Fast Idle Thermo Valve (FITV) and the Intake Air Control Valve (IACV) provide the air needed to keep the engine running.

 

'demon_belial' you'll want to remove the intake tube to confirm a blockage, so use your finger during warm-up and see which holes in the Throttle Body are sucking in air. I suspect the FITV hole will either have low or no flow. Recheck after warm-up, the IACV should be the only one sucking air at idle. Note: the FITV can pull a small amount of vac when shut but nowhere nearly as much as during warm-up.

 

Let us know what you find.

Well i cleaned out the FITV to make sure is cleaned inside after putting everything back in place. I turn the car on now during warm up i notice both holes have suction going trough them. ones the car reached a normal temp i notice the top hole witch i belive it goes to the (IACV) had a small suction and the bottom hole witch i think is the one that goes to the (FITV) had a large amount of suction. when i covered the bottom hole the car just turned off. I tryied it twice and both times the car just died. now im not sure if the way i labeled the holes is correct.TOP hole to (IACV) and BOTTOM hole to (FITV) if im correct then their is defently something wrong whith the (FITV) maybe thats why i dont have a high rpm at first start up when car is cold.i have to hold the peddle for about a minute before i can let go and the car can stay on at high idle on its own.what can possibly be the problem do i need a new (FITV)?
