Water in coil?
I hosed down my engine today and now it seems as though I have a misfire. The check engine light did come on. Now this may sound stupid, but this happened once with my wifes Grand Prix (washed engine, light came on, engine ran rough) when it happened to her car, I could care less. After about a week engine light was off and car ran fine. I guess it just dried up. Now back to my truck, I do care about my truck and want to find out what to do. Will the water just dry up? Or is something damaged, I looked and tried to remove the coils, but they are on tight.
