Do you have something to scan your car with? If not then you need to take it somewhere to see if its throwing any codes. Could be lots of things and we would just be guessing. Your next mod should be an Aeroforce guage or something to scan your car. The pcm wont help your issue and the DP, plog and plugs are not causing this problem.
