So the harness is the same on an 05 and an 06? Just the ECM is different??
What about the dash instruments? Anything else "CAN" system operates?
Motors are the same internally bad mileage could be hard part related. Bad injector or melted piston or both! these motors do a great job of compensating for a bad hole!
