SOURCE: 1997 ford explorer V8 5.0 engine
P1405-Differential Pressure Feedback Electronic (DPFE) sensor upstream hose off or plugged - or cracked.
I believe it is on the driver's side of engine about half-way down. also, check all other hoses for damage

It could be carbon deposits on valve seats keeping valves from totally closing. You can try getting you a can of motorcraft PM3 top end engine cleaner and get engine up to operating temp then remove one of the small vacuum lines from the intake and draw the contents of the can slowly into the engine.After you have drawn in the contents shut engine off and let it soak for about 45 minutes then crank it back up and let it run until it clears. Now it will smoke like a forrest fire while you are doing this so don't be alarmed,just tell the neighbors you are spraying for mosqitos.This may cure the problem. If not you may be looking at a valve job.
This can be verified with a compression test if this is what is causing it.

Look on the throttle body for a little cylinder with an electrical connector on it. Use the handle of screwdriver to give that a few whacks while someone starts the engine after it starts, give a few more whacks. Engine running now? Replace the Intake Air Control motor. or IAC.

Your choke should have a spring at the bottom under a little cover with a rod coming up and connecting to the butterfly for the choke. Usually this get a little corroded and sticks, you need to clean the pieces so that they rotate freely and the rod will move up and down. It is adjusted on some models by bending the rod to make it longer or shorter. When you push down the gas pedal for the first time in the morning it should set the choke, test this by opening the throttle while its cold out, once the throttle is opened the choke should close, once the engine is running there is a vacuum operated linkage that should pull it back some, until the engine is warm. Again if this worked before, its probably dirty so a good cleaning is in order. Hope this helps, let me know
