Thanks, Gaurav.

The TPS does give problems sometimes. Usually you'll notice a difference in the way your transmission shifts if it's an automatic. 

Yes I had changed the throttle body in my own lancer and had to close the screw on top all the way then it was working at right rpm that 2 and half turns are for carburetors not electronically controlled injectors....

I am not that technically well versed with TPS diagnosis, and I shared what happened and cured my stalling and dancing RPM with change of ICV. @Barry, @treks and @shadow79 can you please advise further on above situation....?

Hi gaurav thanks for your reply. Actually i did not see any swing on the rpm .its strange . When i put the shifter in to D rpm comes down around 700 and down very slowly comes down to 630-640 after 5 min in to the D and my food on the brake pedal . Than i put the  car in to the N and rpm comes to 780 and after 1-2 min slowley comes to 890 and then 910 stop. By the way do you think is that related to TPS adjusment. Because the mechanics played with that one time 6 months back. and i believe all problems come from that time. I chacked the voltage of the terminal 3 and ground it was 5.01 or 5.02 and continuity between terminal 1 ground and 2  when the throttle is close completely its discontinuous,(no beep )on the voltmeter.  but when i touch the throttle to open it very very very slowley ( its like touch )  its continuous and complete open is discontinuous.  Is that correct?  Again thanks 

Although bit strange, but nothing to worry. Drive for few days with screw adjustment until ICV re-learn and then slowly release RPM adjuster completely. May be it's just taking longer in your case or I don't remember 100% on how long it took in my case as this is not my daily driver.  Is engine idle rpm (on neutral) has stabilized than before or not? Mine is like stand still at 900ish once fully warm and when on D it drops to 600ish (like it should). Is your engine stalling or RPM fluctuating (dancing) at all now?
