Hey there Mukhtar,

If you have a vibration that you can feel (and see steering wheel shaking) in park I would suspect a problem with one of the following.

1. You have a transmission mount or a motor mount that is worn or broken

2. The throttle body and or idle control motor is dirty and needs to be cleaned to help smooth out the idle speed

3. The base idle speed is set too low and needs to be adjusted

4. There is a vacuum leak somewhere under the hood causing the vibration/rough idle. Look for anything that might have come loose or has broken off under the hood, and listen for a hissing noise under the hood with the engine running. Check all rubber and hard plastic hose connections.

Blessings,

Austin Davis
