Sir, My car has a 1.0 engine. All the things is okay it has great pick every thing is perfect on running, but when I stop on signal on D mode then its start idling or I use power window than it still idling. I do all the tuning, plug change, filter change, but problem still there. Tell me the best solution?

Hello,

I would start by checking for engine codes and vacuum leaks, here are two guides that will help you

This would be for the mass air flow sensor. While you are at it cleaning the mass air flow could help as well.

Here is a guide

If the engine is running okay, it sounds like you might have an engine mount problem. If the engine doesn't vibrate in reverse then check the mounts and get back to me please.
