I have an '02 GP gt , I did the LIM ( thanks to dubobs vid) and the front head gasket here a couple months ago. replaced wires plugs, plenum, ect.
I did not pull the back head off . I have been getting a a backfire-pop when I stomp on it , its hesitates, ect. I took it to a garage and had it put on a machine, mechanic said try replaceing the coil pack for 6, I did that and power seemed to improve, until a couple days later,
I'm kinda out of idea at this point, I have switched injectors and injecter wires and still keep getting this cylinder 6 misfire, is it possible for the front cylinder to be poping and for some stupid reason the computer read it as a cyl 6? At least if that were possible then I would pull the valve covers off and re-check the torque on the rocker arms?

Any ideas guys??

BOUNCE them off me !!!!!!! Thanks!
