Do you mean P0301, P0302, etc? Misfire codes? You have 6 plugs, 3 coil packs, and 3 wires. cyl 2,4,6 are the ones in front, with the coil packs. It's possible they're bad.

Most likely the coils. Easiest way to check is swap them with another cylinder, start it, pull the plug wire connecter and if it doesn't change the engine the coil is bad. If it is the injector, then you can check it with an ohm meter. Touch the leads in the injector it should read 11 to 15 ohms. if you need help let me know.

take the breather off and take a 10 mm socket to take the coil off easy to get to then take a 5/8 plug socket to take out plugs easy to get to,

YOU HAVE POOR CONNECTION AT IGNITION COIL OR ECM.OR IGNITION COIL IS FAULTY.YOU CAN HAVE HIGH RESISTANCE IN THE GROUND CIRCUIT FOR THE IGNITION COIL.HAS TO BE ONE OR THE OTHER.

why would you fix a problem that is not there.if it is fine then enjoy it.plugleads only get changed if faulty.

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.
