You talking engine air filter or cabin filter? Engine air filter is located in air box in engine compartment.. unclamp , open box , remove old filter, wipe out box, replace new filter , reclamp box.
Cabin filter located under cowl just below windshield. remove cowl bolts / plastic rivets. pull off cowl .. filter is in center and slides out like a drawer.. slide in new filter and replace cowl.

2003 mountioneer 4.6 v8 i get a thumping noise from air box off &on

There is a mod for this problem. Insert a 1/2" copper pipe cap with a 1/4" hole drilled in the cap, into the rubber IAC pipe. This restriction helps fix high idle and thumping from IAC valve. Ford has a "muffler in line" fix for this issue, but for a $.50 copper cap, why give $50 to Ford engineers.

Drive down the road and it quit i can get it to start but i have to hold the gas to the floor and then keep it over 2500 rpm to keep it running, the fuel pressure is staying about 45 psi what should i look...

Look for a stuck Idle air control valve. It should be on top of the motor. There are two techniques to work through this issue. One is to thump it with the handle of a screwdriver (if it's stuck this will sometimes help) and the second is to remove it and clean it and replace it. Long term solution is to replace the idle air control valve motor as an assembly.

Also, you need to check for holes in the rubber hose between the motor and crankcase (PCV valve to motor hoses). If anything is squishy soft or oily, that indicates a hole.

Also make sure there are no leaks in the air ducts from the air filter box to the throttle body.

E450 dies when put in gear

Check the idle air control valve motor (usually mounted on top of motor and has wires connected to it). You can thump it with a handle of a screwdriver and if that doesn't temporarily make the vehicle run properly then remove it, clean it with Goo Gone (turpentine or mineral spirits solution for cleaning up gummy residue) and Qtips for your ears, both available at Walmart, and air dry the part for 10 minutes (flammables), then reassemble and try again. Also check for loose fitting air
hose between the filter box and the motor and check for possible holes or small melted thin areas on the rubber hoses between the PCV valve and the motor. These are the most likely causes of the vehicle not idling properly when you put the vehicle in gear.

My 93 ford aerostar 3.0 automatic thumps only when moving. It sounds kinda like a belt busted on a tire but it is not. It thumps while rolling even when the transmission is in N. Any ideas?

You may replace your air filter by a new one or as an alternative, take out the air filter and blow it with an air compressor until all dust and residuals go out. Another known isue might be the amount of fuel that goes inside the burning cabin that is regulated by a litle screw that you can find on a pipe near air vent, go to a pro mechanic to regulate that amount of fuel when the car thumps is usually for a lack of air or a lack of fuel that goes from the fuel tank to the burning cabin.

Blend air door may be stuck. I removed a pencil from a heater box before. It had fallen from the dash, down through the defrost vents and jamed the door.

Thumping rythmic noise from passenger side dash

Don't you just love it: thump, thump, thump, thump, pause, thump, thump...? I've found the best solution is to use compressed air as used in cleaning the keyboard of your laptop. Take a very thin (but strong) metal strip about 1/32" thick and gently place inside the edge of the recirculate button. VERY GENTLY depress the recirculate button just until the thumping stops. Apply just enough upwards pressure on the strip to hold the button in place. This creates enough of a gap for the air to blow behind the button. hold the can of air no more than one inch (1") away from the strip and aim directly to the left or right of the strip. Once you've cleaned from behind the button completely, that mother thumping (LOL) song will be no more.
