The check engine light should be on and give you a code. If not and your vehicle is idling low or rough you should take it off and clean it out before you spend money on it. A good cleaning will usually fix that problem.

At what mileage should idle control valves be replaced?
The idle control valve is not a maintenance part - use until you have a reason to replace. You'll know that when you have a engine trouble code that mentions it as having failed - or other symptoms.

Where is the idle air control valve located on a 1998 Dodge Ram?
Idle air control(IAC) is located on the upper intake manifold drivers side behind the throttle body. That would be for the OHV engine only, I dont know about the SOHC motor.
E350 van will shut off after depressing breaks?
It sounds like the diaphragm it your vacuum brake booster is ruptured. There is a possibility that your air Idle control motor is bad also. After you change the booster and it still doesnt idle right then you know you need to change the latter.
How do you reprogram the idle on a 1992 Grand Marquis?
Reprogram?? I don't know if you can reprogram the idle but there is a idle adjustment screw on my 91 right under the intake.... Try adjusting thatu might need a idle air control valueAnswerThere is no fast idle speed screw on a fuel injected motor. Check the Idle Air Control valve, the Throttle Position Sensor, and the Mass Airflow sensor before you go digging around with the ECM. first 91 has a 5.0 92 has a 4.6 there is a stop screw that can be adjusted but i don not recommend it i would try the above

Don't know what you are asking about the IAC, Idle Air Control, location is passenger side of the engine in the back of the intake. Really a pain to get at but if your idle is out of whack, the Idle Air Control valve either has to be cleaned or replaced.

How do you know if the water you have in your oil on your 91 Chevrolet 1500 is from a blown head gasket or another source?
If the motor will start and idle- let it warm up then carefully remove the radiator cap while the motor idles, if you see small bubbles coming to the surface in the radiator it is a blown head gasket. Replace gasket promptly it can do damage to the motor.
How would you know if the idle motor on a 96 grand Cherokee needed to be replaced?
First off, you need to know that the throttle body is clean. If the throttle body is not clean inside, the PCM (computer) will have difficulty controlling the idle motor. Next, you need to know that the battery hasn't been disconnected recently. If the battery has been disconnected and the engine hasn't been run for a half hour since reconnecting the battery, your computer will have difficulty controlling the idle motor. Now that you've got that part taken care of, lets go on. If you often have difficulty starting the engine but you can start it easily by lightly tapping the accelerator pedal while you turn the key, you probably have a bad idle motor. Do you have a stalling problem and the stalling only happens when you are stopped and the transmission is in gear, and especially if this only happens with a cold engine or only with a warm engine, consider if tapping the gas pedal prevents the stall? Does the engine seem to run very smoothly except for just before the stalling? If so, you probably have a bad idle motor. If your radiator is full and the heat works normally and you have no vacuum leaks but the engine idles very fast with a warm engine, try tapping the idle motor with a plastic screwdriver handle. If tapping the idle motor slows down the idle speed, you probably have a bad idle motor.
