Hey Shelly==It could be many things depending on the make, madel and engine you have.Goodlluck Joe
Always check for vacuum leaks first. If it has a carburetor it is probably time for a tune. check for a stuck or damaged throttle cable. If it is fuel injected you may have a malfunctioning sensor or actuator somewhere. This will usually trigger a check engine light.
Another : Check the A.I.S. (Automatic Idle control) which could be sticking, or the passageways dirty, or defective or worn out. Other than vacuum leaks, AIS or Throttle Position Sensor (TPS), there can be wiring problems or crankshaft position sensors giving false or weak signals.
In older carburetted engines, check the cold idle mechanisms operation and adjustments, like the bimetallic spring actuator or its Plumbing, even the inlet manifold could have some heating passages blocked. amclaussen.WOW! depends on the year and make if fuel injected it can be a throttle position sensor(TPS),IAC idle speed control sensor,throttle linkage,YOUR BIG TOE IS ON THE ACCELERATOR
Could be several reasons but a vacuum leak would be most likely.

Yes - You have a vacuum leak
You could always become a mathematician or a teacher. There is also a high chance you could become a doctor. This could only be possible if you study biology as well. Mathematicians are generally good as accountants too. Anything is possible. You could always become a mathematician or a teacher. There is also a high chance you could become a doctor.

My engine is idling too high. How do I adjust the idle speed?
Any time an engine overheats you need to make sure that it didn't cause serious damage. Run a compression test to see if the head or block has been damaged. Idling high may be a vacuum leak. If there is a vacuum leak and it becomes severe enough, the engine will not be able to start.
The first thing to check if a fuel injected car is idling high is look for (listen for) a vacumn leak. look for a broken vacumn hose. 2nd, check the idle air control (the IAC) - However, if it is a carburetted car then you need to set the idle lower.
Could be several reasons but the first one that comes to my mind is a vacuum leak.
Engine stumbles at idle (Chrysler LHS 1997 3.5L motor idling) could be as a result of a damaged cam position sensor.
