Hey all, I always washed all my engines off at the car wash and I did it again today with my 99 GT 4.6 for the first time and the check engine light came on for a second and went off , the car now is running terrible. Will this go away after the engine drys off? Do I need to set the ECM by disconnecting the battery? Or is it a shorted out sensor that is going to have to be replaced? I would appreciate any assistance as I am a new member. I have had two other Stangs with no problem when engine was washed.
