Started the car today for the first time after completing my Vortech install, got a nice trouble code and an irratic idle. I have a code for coil pack C failure, anyone have a diagram of which one that is? Anyone have this issue before?

 

fixed it, missed a wire.....

 

glad we could help!! Where did you get your s/c from?

 

got it from a guy who got a deal on a gt500 after buying it for his gt
