LLY started knocking very bad and went into limp mode. The truck is not blowing any smoke. I scanned the truck and got P0202, P0203, P0205, P0208, P2149. I attempted to wiggle injector harness 2 and 7 with no change in how it was running. Any input on what it could be? Should I start by replacing injector 2 and 7s harness? Or could it be something more due to the other codes? Bone stock LLY. Thanks!
