Assalam O Alaikum,
I have move 2013, imported in 2017. My car just got issues that it's engine shuts off during driving. Then i go to some renowned electrician/ computer scanner setter. He wash/clean the throttle body, plugs etc(Complete tuning) and scan the car. The problem after that exist. Then next day they just detach all plug/circuits and re plug them , then this issue resolves but they can not say that this was actual the issue was. But after that my car fuel consumption reduces from 19 to 14 with in city with out AC. Then again i go to him and he scanned the car thoroughly. His scanner shows that the car is in ideal condition. But he is unable to give reason why fuel average reduces. Then he suggests me to take the car to a mechanic and might be the "Car tepid" are tight when the car is in cold phase. Please suggest me that what can be the main cause of this reduction in fuel consumption. Thanks
