SOURCE: Ford f-150 running rough
Ok P0174 Is bank 2 (drivers side) is running lean
P0350 is an ignition coil primary circuit malfunction
P1127 indicates the HO2S heater(s) were not on during KOER Self-Test and testing of the HO2S did not occur.Engine not operating long enough prior to performing KOER Self-Test.
P1780 means that the OD switch on gear shifter was not cycled off then on during self test.
I would recommend re-running your self test and make sure to warm the engine up first and make sure to cycle the od switch on/off during the test and recheck the codes.
P0174 lean code could be caused by a miss-fire and P0350 could be caused by anything in the ignition(coil,plug,wires,etc.).
If the P0174 and P0350 repeat I would concentrate on the cylinders in bank 2. If you have a spark tester you could hook it to each of those plug wires individually and look for a weak spark. or try and unhook each wire one at a time and see if you can find a weak cylinder that way by the amount of rpm drop and replace the components on that cylinder and retest.
