I am only getting 11 miles to the gallon! I have replaced O2 sensor, MAFTA air flow sensor, other sensors that I can't recall at this time. At sixty-five mph it will get a slight miss( flutter ). Diagnostic test shows all sensors working but that it is running very rich(930). If you pull the vacuum cap it drops to around(3-4). I have tried Fuel Injector cleaner but hasn't made a difference. I have to fill up every 3 to 5 days and mileage is consistently
11.45 to 11.75 ( Also replaced fuel filter and air filter )
