Long time no posting here. Good to be back
Well 12 valve is more what Im used to. so excuse me for a bit here..

Got a used 2008 6.7 thats throwing me a code: P268c. its bone stock.

Upon reading its a injector part number mismatch. Hooked a scanner to it and it says the injector number is 888888. we did input the correct number and its still throwing that code. we then replaced it with a different injector and input that number into the ecm and its still throwing the P268c code.

Any pointers are helpful.
