Gurus in the house, please help. My toyota camry 2003 consumes fuel unnecessarily. From my home to office is 14km(28km to and fro) and it uses 10 litrs for that single trip. I have changed the air flow sensor, service the injector, catalyst but no difference. What else do I do?

Please stop wasting your money on parts, first run a scan and post the codes here for assistance.

Your Location?

it could be O² sensors, they're are major feedback component in running open/closed loop(whoever asked you to change catcon), could be your throttle body actuator is always @ WOT(wide open throttle), you might have a problem with the ECT sensor(engine coolant temperature), or maybe you even tampered with the thermostat, run the fan direct, for all you care it might even be the ECU (brain box)

a lot of factors may be responsible for high fuel consumption, so run a diagnosis as previously advised

okokobioko! Are you see what i am saw? :-o

The tire pressure should actually improve his mpg because the rolling resistance of the tire is reduced. Its a tool hyper milers use. Op, I know your fuel used, I know the distance covered. I need to know how long (in minutes) it takes you to cover this distance. I also want to know if you switch off your engine when stopped or if you idle till you move again. Cos if it takes you five hours to make this trip, then that consumption is about right assuming your check light is not on. Also stop throwing parts at the car. The money you spent changing all those things could have bought you a small scanner.

just 20-25 minutes drive. The engine light turns on at times and turn off by itself

I'd like you to take this car to chief Gazzuzz shrine so that the gods will cure the car of this anomaly... Hope you know you will appease the chief priest Gazzuzz well. Just do as he says and the gods shall answer your prayers. Ishe...
