Problems after pulling pcu/ECU fuse

Pulled pcm fuse to reset after replacing msf sensor. Now radio interior lights and gauges don't work.

Only connection I can think of is the dead circuit fuse is next to the PCM fuse & got bumped.

Seems everything in dash area including heater, power windows as well.. 2003 Ford explorer 6 cylinder 4.0 Eddie Bauer. Will check to see if I disturbed other fuses

Started right up this morning though. Running rough at idle but from what I've read this is normal

I have no idea how many times I had ECM fuse pulled on various vehicles, finicky capricious hybrids including. NEVER had an issue. Then again, it's Ford and they are plagued with electric issues in wiring. Specifically, fusible links. I join the choir - something got bumped.

Operator error! When I put the fuse back I put it back in the wrong slot.

Possibly more operator error.... if the ECU fuse was not in the proper place.... the vehicle wouldn't run.

I thought of that. According to the owners manual that is the right fuse. Anyway running fine now.

So the rough idle has returned. Thinking I will try the battery disconnect ECU reset. Also read that it could be exhaust leak. Tried listening for leak but can't tell if there's anything, at least not that I can identify.
