Replaced timing chains and tensioners in a 2004 cts 3.6. Engine runs fine cold but when at operating temp sometimes not everytime I come to a stop the engine will shutter and the valves start clacking when I rev it up it stops Only code it sets is P0341. Have replaced intake bank 1 sensor still does it
what issue did you have before replacing the timing chain? Did you replace all 3 chains and 3 tensioners with OEM Cadillac parts?
I would check the harness and the computer, if that is not the issue I would recheck the timing
