The engine is running kind of rough during idle. It seems to be ok while the car is moving but kind of rough during idle. Could you please help me with this problem?

Thank you

You may be having an issue with either worn or damaged spark plugs, or worn plug wires. Typically these failures will show themselves more at idle and appear to go away under acceleration. Also if you are not feeling a hickup at idle in the motor (misfire) and the engine just seems to be rough, shaking the vehcile, then it could be motor mounts worn out.
