Arrow 98 Expedition Starts then stops

Hey guys I have a 1998 Expedition with 94k on it. Here is the problem . When I turn the key the truck sounds like it wants to start but doesn't , so I tried turning the key and stepping on the gas and as soon as I let off the gas the truck stops running . It only happens sometimes , but has been getting more frequent. I have had my spark plugs , Wires, fuel filter and both coil packs changed. Don't know what else it could be.... any input would be appreciated...

First Off, There are two different Engine's Put Inside Expeditions. The 5.4 Liter V-8, and the 4.6 Liter V-8.

If You Have The 5.4 Liter >>


And


There should be Two Bolts Going to the back of it, it is sort of hard to get to, you can take it out, and clean it. Or Replace it.

If You Have The 4.6 Liter V-8
