Re: 1997 Chevy Malibu misfire issue

OK, it doesn't misfire at idle?

It doesn't misfire under a light load? It only misfires under a heavy load?

New plugs were used? Properly gapped?

you installed new wires? And then replaced those? Sure you have the right wires going to the right plugs?

You replaced all 3 coils?

Were the coils new?
