Your engine does not have an idle adjustment like an older vehicle would have. The idle is controlled by the PCM (computer). If you have a high idle issue, then there is a vacuum leak. The most common cause for a vacuum leak that will attribute to a high idle is a loose or broken vacuum hose. A missing vacuum cap on a vacuum port on the engine. Lift the hood and inspect all vacuum lines and ports for loose or cracked hoses's or connections. Sometimes, you can actually hear where the leak is coming from with the engine running, due to the pull of air being drawn in the leak. Also check the rubber intake boot going to the throttle body for cracks that can occur inbetween the ribbed sections of the intake boot.

If you have 150k or more, you probably need a water pump, which is under the seat next to the sliding door. You may not be able to hear it going bad, due to location. I would also switch to 20w50 motor oil. If you live in a high altitude area, it is definitely the water pump. I have two of these, with a combined total of 900k.

This could be a grounding problem. Check all battery connections. Also check motor to body ground strap for corrosion. Check battery to motor ground and battery to body ground. Even if the ground looks allright it can be corroder underneath, so you have to take the ground bolt off to clean it.

mcdevito75 here, Waterpump will not cause over heating unless it is leaking prestone., First make sure you have radiator full of prestone, mixture of prestone on the prestone package, usually 50% prestone and 50% percent water. Most auto parts stores have a gauge you can buy to check the prestone mixture. Overheating can be a faulty thermostat, if yours has not been changed in 2 years, chaange it to a 180 degree thermostat. Also make sure all belts on the engine are adjusted, power steering, alternator, etc as a general rule 1/2 inch play in each belt connected between each pully.

You can chance moving it in your driveway very quickly if absolutely necessary (I don't advise this), but I wouldn't push it further than that. The purpose of the radiator is to cool the water that flows through the engine, keeping the engine from over heating. If your radiator blew and all of your fluid is out of the system, it can no longer keep the engine cool. Once it overheats, you risk blowing the head gasket, warping the head or completely ruining the engine altogether. With no fluid to keep it cool, this can happen very fast.

Hope this helps!
