boss i went to Central automobile on Saturday at 8pm, they were closed, then i went on sunday at 10am they again were closed, so i was very unfortunate i couldnot get my car scanned,
so then i went to friends autos(Khalid) near central automobile so get my car tunned, he checked the pulse by connecting a cable with sensor, he said car is good, no issues. and also get windscreen services and some other minor works
and for flactuation in RPM, it was noticed that VSS sensor was not connected, so he connected the cable and adjusted RPM and problem solved.
