A check engine code has started to show up on a 2008 Shelby GT. The cars has Ford hot rod cams and Kook's long tube headers and cats. There is also has a tune.

Last year, the car threw a code for cylinder misfire. Finally trace to a bad plug ( ??? car only has 18k ) So, the plug solved the problem for a while - now I'm getting new misfire codes.

I've been told it could be a car computer problem and the coil packs.

Any insight would be appreciated.

Who did your tune?

Could be a few things. Coil packs can usually be traced to a particular cylinder. I doubt more than one fails at a time.
