Sorry, Also getting a code
P1142 Fuel Restriction Condition.

I have replaced fuel filter and fuel pressure spring, still getting the same code. I have a diesel site fuel pressure spring installed to bring fuel pressure up to 80 psi all the time. Could this be causing this code?

Here's what I have -> P1662 -IDM EN circuit failure -Open relay, blown fuse, open/grounded circuit

Simplest thing would be to go to the fusebox look at the fuses, maybe swap the IDM relay, then pull the IDM check the plug and look for evidence of water getting into it (you know the IDM is located behind the inner fenderwell, drivers side, kinda behind where the F350 badge is on the fender)
