Why is my car shaking when idle?

If it shakes while it idles, you could be in for a visit to the mechanic. When your car is functioning properly it should run smoothly in all driving modes – moving fast, slowly, stopped and idling.
Why does my car shake at low rpms?
Shaking or vibration may be caused by many different things such as faulty spark plugs, poor fuel pressure or misfires. Other things such as a faulty idle air control valve may cause the engine idle to drop below the normal idling RPM which may also cause the motor to shake or vibrate more than normal.
Why does my car shakes over 40mph?
Typically vibration (shakes) are due to something that is out-of-balance. Given the tires and wheels have been balanced, it could be a wheel bearing vibration, as a worn, loose, or bad wheel bearing could cause shaking. It could also explain the noise getting louder as you accelerate.
Why is my check engine light on and my car is shaking?
The check engine light will come on when any of the following issues are detected by your vehicle’s computer. Shaking or vibration may be caused by things such as faulty spark plugs, poor fuel pressure or misfires. The other issue that may cause this type of shaking or vibration is a broken engine mount.
Why does my car vibrate when I press the gas pedal?
When you press down on the gas pedal to go quicker, your car begins shaking. This is typically due to a problem with the engine mounts or suspension system.

How can you tell when a spark plug is bad?
What signs are there that your spark plugs are failing?
- Your car is a rough starter.
- Your car is a rough idler.
- Your engine will sometimes misfire.
- Your engine surges.
- Your fuel consumption is higher than usual.

Can catalytic converter cause shaking?
A failing catalytic converter can generate a sound that is very similar to a shaking box of rocks. This sound usually occurs when the vehicle is idling or stopped in traffic. You might also hear a rattling sound if the heat shield surrounding your exhaust system components has come loose.
Why does my car rev up and down while idling?
The idle is controlled by the idle air control valve and if it cannot keep the engine idling it will keep trying to rev the engine up to compensate. A vacuum leak, sensor that has failed, or an EGR system malfunction could potentially be the cause of the erratic engine you’re experiencing.
