Mitsubishi Montero Sport 2000 Parts
2000 montero sport engine help?
i have a mitsubishi montero sport with a 24 valve 3.0 liter engine. recently my engine has been running higher than normal rpms at 45mph it runs about 1500rpm now it runs about 2100rpm. also when idling my car shakes and the rpm jumps from 500 to 1000 and back again. i just changed the spark plugs and air filter. all my fluids are new also. idk if its a vacuum issue or a timing belt issue or what ever it is. I would really appreciate it if some one has any knowledge before i just start having parts fixed or replaced
it does have an check engine leak but all it said was miss firee in cylinder number 1 and i changed all the plugs and checked the injectors and when i was changing the plugs i noticed my intake manifold had an oil coating my pcv valve was stuck but i got it working again and i cleaned my egr valve as well shou;d i have these replaced as well or are they fine
Do you have a service engine soon light on? If so, swing by a auto parts store and let them scan it for you with a code reader. Most stores (such as Napa, Advance Auto, etc.) do this free of charge.
It may be a vacuum line blocked or broken, a slipped/jumped timing belt, or need something like a pcv valve.
To add after additional details: Okay, I would wonder first about the injectors. You say that they have been checked, so I will move on. Do you have any strong exhaust odors? If so I would check the catalytic converter.
Here is another idea for you. You sound mechanically minded, so if you are able to try swapping the #1 injector with another cylinder. This will either eliminate or isolate the injector as the problem (and it could very well be an o-ring on the injector.) If this does not eliminate the problem then I would think that you have a problem in a wiring harness, either a defective coil, or a power problem TO the coil. Run it in a dark environment (such as at night, not in a closed garage) and look for any arcing.
Good luck, whatever happens.
