Check engine soon light came on after an oil change
have not found a solution yet. Just sporadically makes the "check engine" light turn on, then it eventually turns off weeks or days later.
Check engine soon light came on. Mechanic checked the computer code and identified leaky gas cap. Going to replace cap.
After just about every fill up, the light will come on. I re-seat the cap, light goes off within a few more starts.
