i have a 94 TT with a bpu kit an torque converter. the problem is, ever since i installled my front mount IC my car would die out if i rev my engine high, then let off the gas. or in heavy stop and go where i have to quickly let off the gas and hit the brakes my engine would shut off. i put my idle at 1200 rpm and that helps but the rpm i too high so i put it back down. any suggestions?
