What causes Trouble code multiple cylinder misfire in 1998 Pontiac sunfire?

Answer 1

This could mean that you have a bad/fouled plug or plugs, bad plug wires, bad coil packs, a misbehaving fuel injector, or a scad of other things.

I'd try new plugs and wires first. It's the cheapest fix and maybe the most likely answer.

I wonder though. It seems that I've seen codes that tell you exactly which cylinders

are not firing correctly. Your code seems to indicate more than one cylinder. That still points

to the things I mentioned above, but also strengthens the coil pack theory, as they feed more than one plug.

If your getting a code 0300 which is what i got.After changing just about everthing it turned out to be the coil pack housing...all went back to normal.$ 43.99 at autozone
