Check the vacuum system on the car an at the transmission. If the car is computer controlled, check the computer codes for a possible problem.

1993 Oldsmobile acheiva 2.3l quad idle low and erratically engine will shut down sometimes when at a complete stop will also idle erratically while mantaining a speed we are clueless help only vehicle?
Check Vacuum lines Also I think there is a "plate" kind of deal on the top of the engine that connects the spark plug wires to the plugs (it lifts off in one piece) and sometimes one of these connectors cracks ( probably due to heat) and that may be the cause of your problem - niot running on all cylinders all the time
Why does your engine misfire on idle?
if its only on idle it sounds like a bad injector
What does the idle air valve control would it stop your truck from running at high idle?
No it will not. It only controlls the idle of the engine.
Why does your 02 Honda Accord vibrates at red lights and stop signs?
If it only vibrates at idle in gear it more than likely has a severe vacuum leak. Can also be a broken engine or transmission mount.

Had this problem with my '87. I believe it was a bad fuel injector.
Does a boat propeller run when the boat is idle?
No, the propeller will only work if the engine is running.
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.
Do you need to throttle the engine in order to recharge freon in the ac?
No............... Just let the engine get to its operating temperature and service it out at an idle only......
Is it normal for an EGR to turn on off idle?
yes it runs off vaccum from the engine, it only works when the car is at cruising speed, not at idle or flat foot.
Why does your car air condition blow hot air when idle?
Your car can only create cold air if the engine is running to make the coolant work correctly. If your car is idle, your engine is still hot but your engine isn't running so the air you are receiving is actually air heated by the engine.
What problem of Isuzu 4BA1 engine the manual trnsmission noisy in second gear only?
a noisy second gear in your transmission is that your second gear might have broken gear tooth which is mostly the problem with my cars.either the second gear on the counter gear or the second gear itself.
