check engine light on but says evap code
I can always tell when someone other than myself has messed with the gas tank lid....either its coiled up all wrong or i ge the check engine light...I then make sure during my next stop to undo the cap and retighten it, making sure it clicks at least 2-3 times. Usually, the check engine light will then go off after a couple of restars after the cap has been retightened.
My check engine light was on so i went to mechanic and it was diagnosed as it being the gas cap. replaced gas cap-problem solved! ;)
