Clean the inside of the throtle body where the butterfly is. Also clean the idle speed control which is on the side of the throtle body. Good luck. 11/11/04 - just happened to me. My mechanic is going to; 1) replace EGR valve He also found a leak (with a special leak detecting gadget) at the intake manifold, so that gasket is being replaced. Check your pcv valve, this on thing can cause a lot of troubleshooting. Only 3-5 dollars to buy.

There are several things that can cause your 2000 Mercury Mountaineer from running. The most common cause is a lack of fuel. You might want to start by changing your fuel filter.

The power steering might whine on a 1998 Mercury Mountaineer because the pump or reservoir is low on fluid. Check the reservoir and add fluid to eliminate the whine. You may have a leak in the system.

Look at your temperature gage...If that is low, you might have a bad thermostat, which would keep your heater from working...I would check that first. also, check the cab air filter. i had the same problem. temp was fine but the filter was full.

The door ajar light might stay on in a Mercury Mountaineer if a door is not shut properly. Sometimes a door will seem like it is shut, but will not be shut enough to trip the light off. Check for dirt or other debris in the door latch for all doors.
