I have a 05 Tahoe with 230,000 miles and my check engine flashing once I hit about 40mph even sometimes before that. I’ve change all my spark plugs and wires and 1 coil pack on cylinder five since it said that one had a misfire. But it still flashes after all that. Some people told me I should’ve got the code clear after getting the job done than some said it was supposed clear by itself it that was that problem. What can be the issue???
Well I need to call with those thousands of different codes. You have to know exactly which one it is so post the code then I can analyze it better
