Ya that's probably what it is. Mine is on when I hit the gas because I don't have catsGeorgia331 said:I have a 95 gt with a 331 and my check engine light comes on after about a minute then disappears when you shut it off so you can't check the codes. My guess is the 02 sensors since I have them placed in the long tube headers.... Any ideas?
Awesome that makes me feel a lot better lol. I had an offload H and "converted" it to catted so that makes senseSlow5.0 said:My check engine light comes on about 4 or 5 minutes after its been running. It's the o/r x pipe that's causing it on my car.
