Get a Haynes repair manual and look up idle speed control sensor. I would advise you to go to your local auto recycling yard because the price of that sensor is about $300.00 bucks.

The montero runs fine but will not idle if you keep it accerated it wont die other wise it will


I had the same problem with mine, I just adjusted the idle speed by tightening the throttle cable at the throttle body located on the top of the engine at the intake manifold. It's ran fine since, about 3 years now and the problem has not repeated itself, hope this helps.

Battery chaged and car DOES NOT idle


when u disconnected the battery u lost the adaptive idle learn program, do the following to clean the intake and allow normal idle

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
