sitting with your car on at an idle is bad over time...the motor starts to overheat because no cold air is coming in and the engine will use all the engine coolant trying to cool itself.. turn your car off if you are stopped for a long period!!!

Engine miss or rough idle, or broken motor mount
Can an idle car engine be damaging to your car motor?
never call an engine a motor. they are two completely different theories of mechanical use. An engine, as in internal combustion engine on automobiles use a fuel to produce power for mechanical work. A motor uses electrical magnetic fields to produce mechanical energy, one the fields have no current flow around them, the motor stops. A car engine cannot be damaged in any way if it is in park and just idling.
Why Car engine shake when AC is on at idle?
The engine idle may be set to low to compensate for the AC compressor starting up. Rev the engine a few times to see if it stops. If it doesn't, there may be a problem with the AC temperature signal or motor mount.

At idle or low engine idle speeds you motor may surge. This could be caused by an air leak in your intake manifold or a bad sensor like a TPS or MAP.
What causes car to idle up high?
There are several things that can cause high idle. An older carbureted engine may have a vacuum leak or sticking choke linkage. Newer computer controlled engines have an idle control device called an idle motor which could be faulty or receiving bad information from other sensors on the engine ( IE. temperature sensor ).
Your 1995 dodge avenger dies on idle what is wrong?
If you have a fuel injected car and you are experiencing stalling, hunting or fast idle problems one thing you need to check is the idle control system. These systems vary from car to car but there are basically two types. The first uses a small idle speed control servo motor which is driven by the computer. When the throttle is released and the rpms begin to drop this small motor moves a portion of the throttle linkage (gas pedal linkage) to advance the throttle so that the engine doesn't stall
What does an idle control sensor do on a 1998 Chevy Malibu?
