I had it to my mechanic and he said it was my gas cap loose, sounds like the auto zone people I know. so i "tightened" my gas cap and had the professionals at autozone 'clear' my code. it stayed out for about 3 minutes and came back on. i dont want to take the vehicle to a shop and pay a professional to have a look because i will get ripped off. I mean I have heard of shops actually charging 100 dollars to diag a vehicle, i want it checked for Free. Does anyone know of someplace online I can research and fix this for free as im on a budget. Even when I had an irregular heartbeat, I said NO to a doctor and went here as well online to try to fix my problem for free. So if anyone has any insight where i can fix my heartbeat issue and my car for no charge, id love to know thanks.
