Still showing misfires. I temporarily swapped in 4 of my LS1 coils on bank 1 and misfires and high fuel trims still present.
Injectors.have about 130K miles, so I'm told. I should probably swap those out for sure.
After all that, victory! I had small gaps in my test pipes. I seen carbon trails so I used foil tape to close the gaps and fuel trims all good now.
