Why is my idle bouncing?
If an engine is not getting enough fuel (this is called “running lean”), due to fuel pressure (regulated by the fuel pump and regulator), restricted fuel injectors, a vacuum leak or really anything that throws off the fuel mixture going in to the engine, this can cause the surge.
What does it mean when your car feels like its losing power?

Malfunction of actuators such as: Bad injectors, bad fuel pump, bad spark plugs.
Why is my car idling at high RPM?
One very common cause of idling rough is a problem with a vacuum hose in the vehicle. The hose could be damaged, loose, or worn out, creating a leak. This could result in an abundance of air mixing with the gasoline, which would result in a misfire. Then, the result of that would be a car that is idling rough or having a higher than normal RPM.
What does it mean when your car Idles smooth?

Rough idling is a serious issue and should not be ignored for a long time. If the problem persists and is not fixed, it can lead to engine failure as well.
What should the idle speed of a car be?
This rotational speed allows the engine to generate enough power to operate vital components without turning off. The idle speed should feel consistent without skipping or slipping. In most of today’s cars, an idle speed of 600 to 1000 RPMs is average. If your car is idling rough, though, it won’t feel smooth.
