Guys i desperately need your help. My margalla 1998 has become a fuel guzzler and gives no more that 6kmpl without ac in city drive. It is a well maintaied car with every function in factory condition:
Working PCV valve
Working tstat valve
Working automatic radiator fan with coolant in system
Stock tyre size with proper inflation
But i am unable to solve its fuel consumption issue. Since the past 1 year, the car has been to 4 different carburetor specialists in karachi and each of them have charged me heavily for an overhaul and butterfly tooling but of no use. I need a tuneup mechanic in karachi, preferably in north nazimabad, north karachi, nazimabad, fb area or gulberg, gulshan, jauhar.
I am fed up of these carburetor specialists and each one of them tries fiddling with the air fuel mixture every time i pay them a visit. a learned mechanic is needed who knows what he is doing. everytime the spark plug tips are inspected, they come out black shaded (even with carbon deposits sometimes)
Please treat this post as a plea since I do not want to get rid of a well maintained car just becoz the fuel consumption is not under control.
