I just recently bought a 2002 montero xls. I had my mechanic check it out, did car facts etc. No problems found. Immediately I started having problems with it. First the service engine soon light came on, needed new catalytic converter, then there was some sort of battery connection issue where the car just died. After those 2 repairs, the car started idling really low at slow speeds and died at complete stops. On top of all that, it runs on or just below 3k rpm when going 60mph. Has anyone else had similar issues? Any advice? Thanks!

 

Not sure about the 3K @ 60MPH. Sounds normal.

As far as the idle though, the idle adaptive memory was probably erased when the battery work was done and the idle air control (IAC) motor is now starting at a nearly closed position. If there is carbon and/or oil build-up around the throttle plate, the amount of air that can flow past it is limited, which causes the poor or erratic idle.

YOU JUST NEED TO CLEAN THE THROTTLE BODY AND THROTTLE PLATE.
