SOURCE: mitsubishi montero sport 99 - car will not start.

could be your ignition switch, first make sure you have power going from your battery to the starter, check at the starter for 12.5 volts then make sure starter has its ground, if that isnt it test the ignition cause thats probably what it is.

SOURCE: how to fix daignostic codes p0304, p0421 and p0455

P0304 is Misfire in cyl# 4. Check your ignition system and fuel system.

P0421 is Catilist effeciency. Fix P0304, if P0421 returns you will need a catalitic converter

P0455 is an Evaportive emission leak. Be sure you gas cap is tight and secure. If it is ok, then there is a leak in the system.

To fix camshaft on montero sport-what would cost


it's not a big job, I would estimate maybe $100. Could be done in 2 hours I figure. I have owned a Mits Mighty max 2.0 for 30 years and that's my best guess. Don't have a shop jerk you around.

1999 Montero Sport XLS jerking into reverse. Error Code says change Transmission Fluid Temperature Sensor


Hi Sc, The job is labour intensive and may solve the problem. I wonder if the fluid in the tranny has ever been replaced? It's meant to be replaced at least once a year. If it smells burned have it replaced. Ask your shop to check the gearbox and engine mountings and in the event of your vehicle having rear wheel drive, the universal joints on the prop shaft. Regards John

Code 400 is for a problem with the EGR valve gas flow or the flow sensor.
