Default Re: Strange P0300 occurrence

When I had a bad ICM on a '93 SL2 it'd run fine for 1ft-10 miles, then the same cylinder would die. Thought it was coil packs, figured out which one was dying and would just swap it out until I finished off my stash (10+ lol), then reused one just to see. The reused one worked for 5+ miles so I was like "WTF?", then just swapped out the ICM and didn't have a problem again.

Dunno if that's been tried...based on my experience I'd go for another ICM before coil pack(s).
