Problem with My Chevrolet No Power When Accelerating Any number of things can cause poor acceleration, or lack of power. Engine misfire- though that would cause a check engine light.
1999 Misfire Codes P0300 P0302 Got a OBD 11 tester and i have a P0300 and P0302, or a misfire in #2 cylinder. Rechecked plug and wire, replaced wire, replaced coil for that cylinder. Sounds a bit better but still idles like a misfire, tester shows a misfire that is the only bad cylinder whats next, resistance?
Check Engine Light Code P0300 on 2005 3800 V6 My 2005 Pontiac Grand Prix has a check engine light on. It also hesitates a little bit. Had codes scanned and came with misfire intermittent on a few different cylinders. We did a tune up.
