when my car is stopped on red light with a normal temperature,at normal rpm,idling is shaking or u can say i feels some vibration on handle.this problem occurs on petrol as well cng.
i change its rpm motor,engine wiring,plugs,coil n coils wire,wash its throttle body,set its tappet, change its pcv valve,and one sensor that i don't know the name of that sensor...i think its located on throttle body for (butterfly motion).but doing such things,problem remain same for feeling vibration on handle,i want smooth idling,without vibration.
plzzz tell me the exact solution or points that i can do for this problem.
thanks...

Check for vacuum leaks and check idle air control valve.

There are several vacuum hoses on the engine. You need to inspect them for damage. The IAC is on the throttle body. It is an electric solenoid that is designed to maintain the vehicle's idle.
