sparkplugs, fuel injectors, coil packs, coil pack harness. if you are getting a misfire code for a particular cylinder, maybe shuffle the parts i mentioned to see if the misfire occurs on a different cylinder. if it does, you'll know what to replace.

always keep a spare coil pack in your trunk. they go out with zero warning.
