CEL on, code 455 2007 Mal Maxx 3.5L
The code 455 is set. Also the radio says "check gas cap". I took off the locking gas cap and put on what I think was the OEM gas cap. Actually I have 3 or 4 gas caps. They are from my 2003 Impala , the Maxx and a 98 Malibu... they all fit..so probably doesn't matter. I have tried all the other caps but one...they all say "check the gas cap". I don't think it is the cap.
any ideas?
