ok ok i sprayed down my engine the other day and now the engine light is on.........i know i didnt touch the alternator..........and the engine sounds fine

 

i kno when i had my engine detailed, my engine light came on. at the time i thought nothin of it. i drove my car home 10 miles and it sounded alright.

well, later that nite i turned the car on and it sounded like ****. i had a bad spark plug
