NotEnoughGPs

Just wanted to say that i have a ton of new parts in it. Map,maf,fuel pump,fuel pressure regulator, crank sensor, icm,coil packs, and I still have this issue where DIC is showing 5lbs of boost while not even on the gas and the fuel trims go negative and than it shuts off and will struggle to start back up for a couple minutes. I was going to change PCM but thought I would try to talk to you about it since I saw your thread about having the same issue but never saw a post about what actually fixed it. (Also I have checked pcm grounds and they are all good)
