please if anyone knows any advice i need some help on the way home from work tonight just driving along in the cold and snow and the check engine light came on and truck started running like a ford. Runs real rough cutting out and no power at all. barely made it in the drive way. Shut it off and checked the codes with the smarty and came up with a P0305 #5 cylinder misfire and a P2149 unknown. any ideas please help thanks jared.

 

P2149-BANK 2 (CYLINDERS 4-6) SHORTED HIGH OR LOW
P0305-CYLINDER # 5 MISFIRE
misfire detected at cylinders 4, 5, or 6 or any combination of cylinders 4, 5, or 6.
Disconnect the pigtail nuts from injectors 4-5-6.
Check connectors - Clean/repair as necessary.
NOTE: Be sure to zero the ohm meter prior to checking the injector circuit.
2. Measure resistance of each circuit in the injector harness from pigtail side to injector harness connector.
Is resistance above 1 ohm?
Yes
Replace the injector harness.
Measure the resistance between the solenoid posts of each injector.
Is the resistance less than 1 Ohm and greater than 0 Ohms? No
Replace the fuel injector or injectors
