Excessive Fuel Consumption

[spinmaker5]

Hi all I have a Chevrolet Cobalt 2.4 2009 ls xfe with some 17 inch rims and an aftermarket air intake. I was wondering if anyone knows how to read live OBD2 live data or tell me why my car uses excessive fuel around 9.2/100. I independently changed the variable valve solenoids both, i change the map sensor, camshaft positioning sensor, ignition coils and spark plugs, and upstream oxygen sensor, coolant theromostat and thermostat sensors, put in fuel injector cleaners, but still car is eating fuel.

That sounds within the range that car should get (25mpg in Freedom units lol). Have you cleaned the MAF sensor recently or changed the air filter?

Yeah i have an aftermarket intake with a filter and a new and i cleaned the mass flow air sensor. It doesnt feel like 25mpg. More like 16mpg. ill give you values. This is obd 2 reading between 2000-2500 rpm.

Yeah it's an app average 9.2 but it doesn't feel like it

Afraid I don't have a lot of ideas here. Make sure you have recently changed the oil and transmission fluid.
