rpm is not controlled below 1400 by any workshop. dealerships recommend to change it. they fix the rpm but after a few it drives again rises. without accleration it must be at 900 approx. but it remains at 1300-1400 rpm.
i bought and replaced it at bilal gunj for 5000 10 months ago,but its also of the similar fault. Can you recommend me a place where i get it done satisfactorily.
