Bump !!! Average dropped to 2.7kmpl and mechanic is unable to diagnose the problem ,he kept on resetting ecu (by removing negative terminal) after scanning .thats it ,, i opened MAP sesnor by myself but didn't tried cleaning it because i only have carb cleaner at the moment and i don't think so something is wrong with map because nothing is wrong in scanned results and no check engine light ,kindly helpp liana is killing me ,
