I'm having the same problem with mine. I had had it happen a few years ago and it healed itself, but it has once again presented itself. The mechanic told me it's probably the idle air control. He said you can clean them. It's right at the top of the motor. Takes about 3 minutes to remove it and 1 minute to clean it. Worked first time, but it still does it on occasion. I ordered a new one. I wouldn't recommend driving it like this as the oil pressure gauge bounces around when the idle goes really low. Probably damages internal engine parts due to low oil pressure. 38 bucks from Rock Auto on my 1995 5.8 liter.
Good luck.

I just recently bought an 86 with a 302. It's a project. As of now it runs, but is rough. I'm in the process of taking out the engine due to bad a freeze plug (leaks coolant). While I'm at it I will redo all the gaskets and tune ups.
This truck is sitting on 32s and has a jacked up control arm. I agree with you about it not being the manufacturer's problems. This rig was offroaded and abused. Due to it being a Ford, she still runs. And I shall restore her :-)
