I had a similar issue when I installed chips in my ECU turns out the ECU had some water damage causing the light to stay on the car ran fine, I just had to stare at the CEL. What company's chips are you using? Sometimes it can be a bad checksum in one of the chips.<ul><li><a href="http://www.sjmautotechnik.com/trouble_shooting/ecuf20v.html#20v_check">http://www.sjmautotechnik.com/trouble_shooting/ecuf20v.html#20v_check</a</li></ul>
