Good morning, I have a question for you, I have a F 150 1995 4x4 4.9 5-speed, the question is in the field of consumption, my truck consumes way too, something like double or triple of what appears on page www .fueleconomy.gov, even I could not taste good but with 11 gallons do 70 miles, is that everywhere I see that with 6.7 gallons would have to do 100 miles, someone knows that can be wrong with the truck, the injectors are new, spark plug, spark plug wires coil all new and original Motorcraft, no longer left to do. tested vaccum in manifold and its ok too, could be an electrical problem?? thank you very much for your attention!!

Mine dropped a few miles per gallon when I switched to bigger tires. Also I think my downstream O2 sensor has been disconnected when the transmission was done. My engine light is no longer on and it does not run as smoothly. I have OBDII and it won't even pass inspection. Anyway those two things I think dropped me from around 15 mpg to 11.

You should have OBD1, you can read the codes yourself - that would be the place to start. The computer has a self diagnosis function so that you don't have to guess.
