its normal to have 900rpm. if on aircond should drop to 800rpm. if ur car is new enough,normally will not feel or see the vibration. when ur car is getting older even like 2years time when u idle u can see the steering vibrating. normally this vibration is on idling only. if u are in gear it wont vibrate.Proton fuel injection Idle Control, Engine idling adjustment procedure
