Heads up about that fuel injector swap on the 6.7 Cummins...

I just spent 3 days chasing a rough idle on a 2016 Ram 3500 when it should have been a 4 hour job. Turned out the new injectors I put in were fine, but one of the ground straps under the valve cover was corroded and barely making contact. I about pulled my hair out swapping sensors and chasing wiring diagrams. Has anyone else run into a stupid little ground issue that ate up way more time than the actual repair?

Man these trucks really know how to make you feel like an idiot. Bet you were ready to throw the whole thing in a lake by day two.

Man that is brutal. I had a similar thing happen on a 2015 F250 where I swapped a whole fuel system just to find a rubbed through wire under the cab. Three days of my life I will never get back. You spend all that time chasing the big stuff and it is always something dumb like a ground strap or a loose connector. Makes you want to kick the truck and then apologize to it.
