Car is missing at idle, always does it when I don't drive it for more than a few days, I lay into it for a sec and its always fine. Was down for a month waiting on master power to get my turbo back. Well while I'm at it I toss a bosch 044 at it to replace my loud ass mallory fuel pump. Well I start it and hear a miss, check fuel pressure (41psi with no vac). I have tried the following:
Plugs
wires
Coil
ICM
Bypassing the MSD box

Still nothing, sorry for the long thread but can someone help me? It won't let me go past 4500rpm wither. I have a 1 year old AC Delco opti with maybe 6000miles on it btw.
