I have an idle problem, exhaust clip inside!
I have an idle problem, exhaust clip inside! So my car still isn't running like it should. I took this video to see if anyone can listen to the way the exhaust sounds and help diagnose what the issue is. Just some background on the car/motor: Bored .020" over, heads decked .010". 2001 pcm with '98 cam. TSP 1 7/8" longtube headers with 2.5" ory and 3" slp loudmouth exhaust. I have already checked and double check both my cam timing and my intake manifold and check extensively for vacuum leaks. When I start the car when the motor is cold it starts and stays idled very well, just sounds camed. When I start the car when the motor is warm it starts, then rpms drop below idle and the motor either stalls or comes close, it does that for a few seconds and if I tap the gas a little bit to keep it idled and do that for a few seconds it will idle. While driving once the motor is up to operating temp it will occasionally try to stall when I put in the clutch. Sometimes after I start it when its warm and start driving the car hesitates and stutters with light throttle and then just wakes up with slightly more throttle, but then acts normal a few seconds later and doesn't reoccur. On the other side it seems to run well under load and WOT. Here is the exhaust clip. Please help!

to fix the hot start problem you need to add some airflow in the temp areas that the problem happens. Like in the 160-230 degree range. Do you have any tuning software? If you have EFI Live I can fix the problem for you.
Ok thats what I thought but I had one guy tell me different so I was just trying to get a couple of different opinions. Thanks
