My car near to see is very expensive gasoline, as ordinary cars go 45-50km to spend a gas line is now only about 30km. I filled the tank but only run about 300km. This is too costly.
I replaced the wind filter, petrol filter, iradinum spark plug, gas throttle cleaner, wind sensor, but not feasible. I plan to upgrade the ECU software, would anyone please share it to me or advise how to fix it.
