- I have a 1999 7.3 f350. The crankshaft broke so a "newer" motor has been installed. The truck starts and runs, but has a slightly rough idle (some shaking and just not as smooth as it used to be) and is giving a p1316 code along with the general idm code. The shop put new valve cover gaskets along with the harness, the injectors were redone at full force diesel, it has a dp tuner that was updated with the injectors, I was told buzz test was good, injectors ohmed out good, all wires on uvch checked, the idm was swapped out. The shop has been checking all pins and wires but no luck. Any thoughts? Thanks, Leigh.
- I've gone through a lot of the other threads about p1316 issues but don't see anything else.
