Pcm p0300 misfire code
Hello guys,
I need some help finding why my Cadillac Deville has a flashing ses light and also is misfiring.I have replaced all the spark plugs and both ignition coils front and back.Could a oxygen sensor cause this problem?Could this abs code cause this problem abs c1218?I would really appreciate any help about other things to check.The ses light only starts flashing when I got over 20 mph...when idling it does not flash...
Thanks
