'01 dodge neon engine missing?

They will get a P-code, I don't know how much more specific you'd want.

I think a code for cylinder 4 misfire is a pretty good indication. ;)

Pretty much says, check the plug, check the coil, check the injector, check the wiring to those things.

OP - good luck! In my case I was just getting a P0304? misfire on cyl # and putting new plugs/wires/set of injectors/coil(s) didn't do a thing. Even checked compression and it's even on all four. It misfires hard enough to notice it running rough, and it does this usually right after filling the car up.

Didja check FP Jean? Maybe a sticky injector. Or, valve adjustment. Was there a random misfire code too?
