you One more thing about which I am highly disappointed. If the throttle body is at fault then it has to be replaced and it cant be repaired. Whole damn throttle body is sealed and no sensor can be taken out or cleaned or replaced.. Even if throttle position sensor goes bad whole throttle body will be replaced. and the price of throttle body is close to INR 27000 :A .. When i was told this I was like "Is it some sort of a damn joke!! " . I showed this problem to another mechanic who is a very good mechanic and deals only with the electrical in car he told me that 99.99% it is the throttle body only or if i am lucky it might be the accelerator paddle potentiometer. I really dont understand why fiat has put this kind of part which is so costly and even if a small sensor fault comes whole damn thing has to be replaced. - - - Merged Post - - - Karan does your car used to stall also few times???
