There are many possible reasonss for high fuel consumption.
1. Driving condition and habit. If vehicle is mostly driven in city traffic, fuel consumption would be higher. So would be a brisk driver who is heavy on the gas pedal.
A). Mechanical. Any fault with engine mechanical would cause losses in engine performance and higher fuel consumption.
B). Tune-up. Some high fuel consumption problems can be rectified with a tune-up.
C). Transmission fault. If trans is slipping, it would be so.
As to the meter lights coming on and off, it couls be a loose connection somewhere.
