Re: code 15 after header install
hey guys just wonerin if ne one could help me out, im still getting the ses light every morning till the car heats up to about 150 or so degrees, im thinking maybe the o2 sensor isnt getting a proper reading cuz with thses headers (edelbrock tes headers) the o2 sensor is positioned lower than the original exhaust manifold
