ZO6 throwing ing coil codes hafter header install???
I had a set of longtubes put on my car yesterday, they put new plugs and 02 sensors in and i noticed driving it home last night it was missing at WOT starting about 5500 and feel flat on its face. also noticed that if i turned left the car would act like it wasnt getting fuel(kinda spit and sputter) so this morning i went to start it and it would even start. it would fire up but just kept dying and if you gased it to keep the idle up it felt like it was only running on 3 cylinders? i finially got it to throw a CE light and it was a P0300C miss fire code and 8 other ing coil codes

Follow the main wiring harness on the drivers side of the engine, on top of the manifold to the back of the engine. There is a black metal bracket at the rear of the fuel rail that the wiring harness bends around.
See if that bracket has cut into the harness and damaged the wires. Common issue!

Have you checked the electrical connections for the coils? With those codes that is the first place I would look. I doubt it would be the plug wires cause you would have got codes P0301 up to P0308 showing which cylinder was mis-firing.
