Stock civic dx
I just changed the plugs, and air filter. The next day someone cut me off and i gased it and now the check engine light comes on everyonce in a while. Its driving me crazy! The oil does need to be changed but I am doing that this weekend....does anyone know how to read the obd1 led light? Please let me know any advice.....the light stays on after the car warms up....and not everyday...very strange. I am thinking the o2 sensor.
thanks!

 

uninstall teh ecu an battery.. an reinstall it.. if its still doin teh same thing.. its probly ur 02 sensor.
