I cleaned my engine with a degreaser, hosed it off, and it started and ran fine. Drove for about 1/2 hour to Home Depot. Got back in the car, and it ran very rough (misfiring). Drove for a few hundred yards. Got back to the car, tried to start it and no go.
Is this something related to ignition parts getting wet? Could something serious have happened when I cleaned the engine?
Any advise would be helpful.
