Hello everyone,

Recently I've bought an old mitsubishi Space runner 2001 2.0i - 136hp. Everything was OK with the car when I drive it at low rpm - about 1500-3000, but when It hits 3000 rpm and above the "check engine" light turns on and two of the cylinders stop working. When I turn off the engine and start It again everything is OK and "check engine" light is off. It happens at any speed or gear once It hits 3000 rpm (and keep rpm at about 15 seconds). The computer says that It is crankshaft sensor so I change the sensor, but the problem remains. I also change the coils, but situation is the same. I would appreciate any help and advise.

Thank you,
P. Ivanov

Do you know if it has both crankshaft AND camshaft sensors (95-99 Eclipse 2.0 engines had both of them)?

If you do have two sensors, I wonder if you replaced the wrong one?

Stop guessing and download the engine codes. You can have any number of problems and by parts swapping it will only complicate things.

Jim, sounds like he did download the codes, but perhaps changed the wrong sensor? :unsure:

Sorry, I missed that bit.

I have had several cars that have lost power at higher revs; it's been a partially blocked fuel filter.
