My 2000 Expedition sputters when accelerating. Is this a clogged fuel filter, injector or timing belt problem?
Do you
have the same problem?

Hi:
Before considering a fuel problem, what size V8 is it and is the check engine light on?

Has anyone "washed" your engine?
If it just shakes alot it's (probably) a COP (coil-on-plug) or spark plug failing.
If it FALLS FLAT -check fuel pressure - it's very easy - there's a shrader valve (like a tire valve) on the top of engine - just slip a guage under the wiper and go, being careful not to turn on the wiper if it's raining.
To check COP's (and other ignition/fuel checks) you'll need to have a scan tool that shows at least a code for what cylinder to check, or better yet that shows crank speed and tells which cylinder(s) not contributing in real time.
These are both common problems and is where I would start. (There are many more [less common] things that happen)
If you pull a COP out and the boot has a big crack - replace ALL the boots. (COP's are OK)
If pressure IS going away don't just replace the filter, replace the pump at this mileage if not been done before.

My 2000, 2WD, EB, 4.6L Expedition 139,000 miles sputters idle, in gear and while driving. Fuel system cleaner has no affect. Appears I would have to disconnect the fuel injection to change spark plugs. I posted my own question as well. Can someone confirm the need to disconnect Fuel injection to change plugs?

Hi:
You should be able to work them out without removing the fuel rails. I have the 5.4 and thought the same thing, but was able to do it.
