Well, for the second time in 6 months, my check engine light came on for nothing more than the gas cap. Has anyone else had this happen? The cap is good and tight at fill-up, just got that code again. I'll remove the code, make sure the cap is on tight, and the code will come back in a few months. Heck, throughout that time it's removed/replaced many times for fueling. Why is this happening? What's the answer, a new gas cap? If so, should I get one from Dodge or will one of the aftermarket brands be good enough? Just curious if anybody else has seen this too. Have a great Memorial Day everybody!
