2000 F150, 4.6L Triton, 165000 miles The truck rus good, I have no trouble codes. Fuel pump just replaced due intermitent operation. The mileage porblem has been apperant since I have had the truck at 135000 miles, 1 1/2 years ago. Mileage averages about 18.5 to 19 during the summer, and drops to 17.5 or less in the winter. The colder the weather, the less mileage. When the wather warms 20 degrees or more, the mileage spikes, but then drops back to whatever average is for that temp. Driving conditions are always the same, as I work at an office and use the same route each day. My suspician is a bad Mass Air Flow Sensor, but I would like to know how to verify this before spending the bucks to replace it. I had a similar situation with a 1993 Ranger. I would attribute it to local fule mixing, except for my 1996 escort that never varies in mileage. Any suggestions?
have the same problem?
