Tonight i was *driving* around wtih 7 other mustangers and my service engine soon light came on...now last sat. i got my mac prochamber put on and ever since then when im going aroung 20mph or so and ease in on the gas the car will shutter and feel like its gonna stall (im an auto btw). im just wondering could the exhaust have somn to do with it? my buddy who put it on is coming over 2morrow and take a look see, just wanted to see what everyone thinks. im just very pissed off cuz its my baby[:@]

Well I guess you will just have to go to Auto Zone and have them scan your code for you so you can find out whats up then maybe we can help.
