10mpg wtf!

[2000_f350]

OK like out of no where my milage dropped to like 10. This is with my Edge set to stock and I keep my foot out of it most of the time. Will a fuel filter cause this?

[JJR]

Yes it will but you would notice a lack of power. Don't know your mileage but worn and dirty injectors can cause this too. Check fuel filter and try adding some Seafoam to your fuel tank.

If you have 4x4 are your hubs locked? Do you feel the truck miss while cruising?

[2000_f350]

Truck feels fine. Idle is a bit rough. But I think it's always been that way. Still has enough power to smoke the tires. Could a fuel filter cause this? I did add power service to this fillup. I don't know but something has changed. No service engine soon light or anything. I should get better than 10 with no tune and a lite foot rite?

if your not towing i would think you should get atleast 15mpg i think i get about 16 to 18 with my late 99 f250

does it idle rough on cold starts? if so, get a re flash. that will help your mpg's. also check your air filter. a dirty filter will drop mpgs.

can a faulty icp sensor cause this, ive heard this somehwere dont remember tho

I put a diy intake on about 2 weeks ago. It's clean. It runs a bit smoother when it's cold. It also starts faster. Any of this info help any?
