Question about 2003 Mitsubishi Montero Sport
I have a 2003 Mitsubishi Montero Sport LS, V6, 6G72 Type, 3.0L, with 2WD. The check engine soon warning light energized, and an OBD 2 revealed the Code P0305. Possible causes: Air leaks in the intake manifold, EGR or PCM Systems. Mechanical fault of the cylinder. Fuel Delivery Fault, or ignition fault. I've replaced the PCV Valve, Spark Plugs, Wires, Ignition Coil, and Fuel Injectors. Where else could the problem be?
SOURCE: cylinder 2 misfire
One often overlooked item is the spark plug leads themselves! They don't last forever - Some start breaking down internally after only a couple of years, and although you still get a spark at the plug, it is not a very healthy spark.
If they haven't been changed, it is well worth giving it a go.
Hope this helps!

YEP BAD COIL CLOGGED FUEL INJECTOR AND INTAKE LEAK TO CYLINDER 1.TRY CLEANING FUEL INJECTORS.IF STILL MISFIRE DO A COMPRESSION TEST TO THAT CYLINDER YOU COULD HAVE A MECHANICAL ISSUE.
