I was wondering if anyone knows the procedure to do a diagnostics check on the S13? My check engine light turns on intermittently, and has no effect on how the car runs or on gas mileage (22-25MPG consistantly). I have taken the car to a shop, and they said a code reader is not required to check the ECU for engine codes.
I need to get this problem sorted out because the check engine light has caused me to fail smog twice already even though everything else checked out perfectly.
