I have never had a peoblem with my car until I had a slight wreck with it... I hit a fallen over tree that was in the road, sent it to a shop and they said they checked it all but Im not sure. Basically I will be riding down the road in say fifth gear and push in the clutch to come to a stop at a stop sign and it will just die. I tested it with the air on and with it off and it does it much more with the air on than with it off. I have a cobb AP on it set to stage 2 and I get one CE light that comes on each time I put gas in it and it tells me that I have a emissions leak that the gas cap is loose or off.. I reset the computer and codes tighten the cap and it goes out.. Not sure if that has anything to do with it but just thought I would throw it all out there so I can get some help on this issue I am having.. Thanks in advance for the help guys..
