P0305 Misfire in Cylinder 5

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!

"Check Engine Soon" Light in the panel board suddenly turned on.


Sure.
You need to have someone scan the computer for trouble codes. Most auto parts stores will do this in hopes of selling you some parts.
Once you get the code or codes you can research them online.
The codes will point you in the direction of what to inspect, not what to replace.
