N14 misses at low rpms only when driving
N14 plus misses at lower rpms only when driving.... When parked and rev the engine seems fine... But when driving it sputters at lower rpms and clears up

What year N14? Sounds like the all to common failed injector(s)

Disconnect one at a time, till the miss is gone
That’s the connector on the drivers side of engine

It's hard to find when the truck is parked.... It only misses when driving

Do as HHOW describes - Unplug 1 and take it for a short drive. Keep stopping, plugging it back in and disconnecting the next one until you find the culprit.

If it ends up being an injector, buy one with PX in the part number instead of RX. The RX ones tend to last about 5 minutes longer than the warranty period.

There a fuel leak at my shut down solenoid.... Can this cause air to go in the fuel?
Did a cylinder cut out test with insite and all injectors seems fine
Can air go in the system from the pressure side... Since the solenoid is not on the vacuum side of the fuel system
