2002 Chevrolet 2500hd 4x4 6.0lt.

I have a po306 misfire. I have replaced spark plugs, spark plug wires,ignition coil,fuel injector, and wire harness. And truck still misfires! After running truck for a while, truck starts working correctly but sometimes. If I plug #8 coil wire to #6 coil wire , #6 starts working but if I plug back #6coil wire nothing happens. Can someone please help a fellow chevy bow tie brother out? Thanks.

  Took some leg work, but I guess they want to keep my business.

  Sounds like a nice deal in the end.

  Have a look at the Diode Dynamic C1R light. It installs in minutes with their wiring harness and is super bright when backing up. I leave mine in all the time for an extra brake light and pop it out when towing as it sits in my hitch receiver. https://www.diodedynamics.com/hitchmount-led-pod-reverse-kit.html?srsltid=AfmBOoqycZjgNgKE-vDJIzGAP-DXvFCp8LygfNFp0m6YVgkxeIkJt1jC

  Guys, thank you so much for the help! Dealer called back and is willing to participate $7,000 towards lifter and cam shaft replacement. Basically complete engine rebuild. Our cost will be 5k. These replacement parts will be covered by a 3 year 36,000 mile warranty.
