Well, im clueless with whats wrong with my car, so maybe you guys can help me out. I have a miss that starts at about 5 PSI. The car will miss when the motor is cold or warmed up. I changed crank sensors, unplugged the cam sensor to see how it ran, tried 2 different ignition modules, 2 different coil packs, put my stock 85 ecm back in with the 85 maf and still had the same problem. I also replaced all the spark plugs but not the wires yet. The wires are AC Delco, and I out them on less than 2 years ago. I check to make sure my 2 week old Walbro pump wasn't crapping out, and the fuel pressure was good. Everything looks good on WinALDL. Any suggestions?
