just did a few upgrades cam lifters springs polished intake upper plenum 70mm throttlebody trans rebuild and 2800 stall. i just got the car running after one aggravating headache after another and it seems to run really strong but the idle at times get very irratic sometimes high sometimes low i've tried adj. tps and iac nothing seems to be working. also when i go to WOT and let off suddenly (example when in town doing some showboating from light to light ) my car continuously wants to cut out unless i feather the throttle alittle it will do this almost all the time. the more perfomance parts i've been adding this problem has progressively gotten worse. it seem that for some reason the more partsi put on to help spool up or increase the volume amount of air into the engine now when ever the throttle close after some boost the engine shuts down. please help this is quite embarassing to have a bad ass car that stalls when trying to twist some air.
