Problems or Dealer Service
Hi Everyone,
I'm a nub so bare with me. Here is the problem I have. I have a 2012 Shelby Cobra GT500. It has a 5.4 with the Super Charger,
I have owned it for about 2 months, It has a cold air intake, smaller Pully, and the cats removed all done by previous owner.
I got the mis-fire on cylinder...
