Hello all I'm back again with a new/old problem. I have a 2003 3.1l with 173,000 miles.The other day my water pump went out on me on the freeway and the car shut off. I limped it home. Drove it to the auto store the next day, it was overheating, andback home. Replaced the water pump,and a couple hours later went to fill it with water. At this point I accidentally sprayed the coils and top of the engine pretty good with the hose.
After filling and bleeding the system I noticed a check engine light came on and began blinking. I pulled the code and it was a po302.
I checked for spark at the coil pack which it had and then I pulled the plug. The plug was fouled up pretty thickly and it had wet fuel on it that soon evaporated. I replaced the plug with a new one and the car ran good for about a block, no misfire at all according to my creader crp123 but then started flashing the service engine light, and registering misfires on 2 again.
Any clues aside from you shouldn't run water in the cooling system? Oh and I've bypassed the heater core and removed the thermostat btw.
Thanks!
