2003 Impala has random misfires!!!!
Car has been lacking power lately. If I bring rpms over 4000 it starts to break up pretty bad. Acts like it's bouncing off rev limiter? Scan tool shows cylinder 1 and 5 have misfires in the history counters. Fuel pressure is over 50 lbs and does not change when motor starts to break up. So far I have replaced plugs, wires, crank sensor, coil packs and module with no change. If anything it seems like it is getting worse. Any Suggestions? Thanks, Art.
