'98 Saturn SC2 stumble on heavy acceleration
I've had this '98 Saturn SC2 for a couple weeks and it'* been running fine. Just today it started stumbling on heavy acceleration in 4th and 5th gear. It wasn't setting a CEL, but I put my AutoXray scanner on it, confirmed it wasn't setting a misfire code, but then brought up "Operational Data" while the engine was running. Under that information it was showing misfires on Cylinder 3 (no other cylinders). Any ideas.... I'm thinking maybe a bad coil pack? Normally a misfire on 3 would set a CEL of similar to a P0303 or the like?
