oh and the code for the gas cap loose CEL is P0457 ... I wish you the best of luck with your mustang...

If it wasn't from gas cap (filling up) I wonder what the hell this is? What did the dealershipdo to yours for the P0456 code? Did they fix anything or just reset it?

Thanks for the info.

They didnt do anything, they just reset my computer and sent me packing... but... I did have to go in a second time because of other problems that triggered... they figured that the throttle body was the cause.. they are replacing my entire throttle body and sensor (warranty covered)...

Engine light back off after 5 days (went off on it's own). Don't leave the key on while filling up.
