Is 2000 rpm idle bad?

Why does my car idle at 2000 rpm?

What RPM is too high for idle?
Typically, engines idle at about 600-800 rpm. Older engines may go up to 1200 rpm or more while warming up. But if the engine is revving up while idling, even after it’s sufficiently warmed up, you might have a problem. High idle speeds waste fuel, cause extra wear and tear on your engine, and can be unsafe as well.
How do you fix high idle after cleaning throttle body?
The idle will relearn if you put the vehicle in drive and allow the idle to come down with all accessories off for about two to three minutes. Then turn on your a/c with blower in high position for three minutes. This should fix it.

What is normal idle rpm?
Does high rpm hurt engine?
While extremely low rpm and high loads will damage your transmission right away, sustained high rpm may damage it over the long run. High rpm means more wear on the bearings and oil seals, and quicker transmission fluid breakdown.
Can spark plugs cause high idle?
If the spark plugs are bad, then the electrical current won’t be sufficient enough for the ignition. This will cause the fuel and air mixture to burn inconsistently, which will result in rough idling engine.
Can a vacuum leak cause a rough idle?
Unfortunately, air leaks sometimes occur in an engine. Such leaks, which go by the name of vacuum leaks, throw off the air-to-fuel ratio. Specifically, by allowing excess air into the system, vacuum leaks create a lean fuel scenario. As covered above, lean fuel can lead to misfires which in turn lead to rough idle.
How do I relearn idle?
- With the vehicle at a complete stop, set the parking brake.
- Put the gearshift in P (Park for Automatics) or Neutral (for Manuals), turn off all accessories and start the engine.
- Run the engine until it reaches normal operating temperature.
- Allow the engine to idle for at least one minute.
