Question about 1999 Saturn SL
99 Saturn, 'Sevice Engine Soon' light, PCM code P0404. Car runs fine. Erased code. Driving car now and light/code has not returned. Any suggestions on this possible problem. Thanks
P0404 - Exhaust Gas Recirculation (EGR) Open Position Performance
I suspect the EGR got stuck closed, u will need to put around 30 miles on the car before the light will return if the problem is still present..
