94.5 runs rough

Been having a problem had a dead miss when pulling a load or reaching 60 mph or more. Did a CCT on it and found #6b had an inbalance fault. Put injector in #6 hole and did another CCT to check and see if problem was fixed before i drove it. Same code came up and thought it was a fluke cleared codes and ran test again and then had multiple cylinder codes come up. Think it might be valve cover gaskets and UVC harnesses did not ohm them when had it apart. But the codes are for injectors on both banks. Kinda stumped.

Make sure the engine is up to normal operating temp before doing the CCT. I would check the UVCHs, VC Gaskets, and external harness connections. If any of the connections are burned melted, replace the gasket too. Cheers!

Agree with Patrick. Just pull the four connections and smell them and see if there burnt you will know FO SHO! When mine went out my truck had ZERO power and would barely idle its was sketchy I think I lost 2 injectors.
