Re: 1993 2.3L Trouble Code 224
Okay, thought I would follow up for those of you who might have the same type of problem.
I Checked the primary resistance of both coil packs and all four checked good (less than 5 ohms). I check the secondary resistance of both coil packs. 13.5 K ohms on all four. I'm not sure what the spec is but that sounded reasonable. I took a chance and replaced the ICM (DIS module) for $140. Code cleared and truck runs good.
Hopefully this may help someone else out there.
