How do i test if my coil is bad. I did a test on my spark plug wire and they are in fair condition (read 2-3 ohm).

Are you getting any P*** codes? Is it missing at idle or while driving? You can remove the coils one at a time to see if there is any corrosion under them, between the coils and the ICM. Sometimes a little corrosion may impede the spark. Cleaning this with a piece of emery cloth with restore a good contact point.

Has your gas milege changed much? Running some gas treatment, like Berryman's, will clean the fuel system out. Sometimes just getting out and blowing the soot out of it helps.

bbob, may have a suggestion for as well, if he sees your post. I bet he will.
