The problem with this truck? is that when it first starts it runs fine But then it starts to bog down like its starving for gas but no backfire, The farther it goes the worse it gets, pull over, shut it off restart everything is just ducky for about a mile then the bogging begins again. New fuel pump and new fuel filter- no change. so far. Any ideas? It is a 1993 Explorer 4x4 automatic tranny w/ 158,000 mi on it Has the 4.0 pushrod engine. Any help would be appericated.

Have a back pressure test done on exhaust, sounds like a plugged catalytic converter

Exactly. If you don't wanna pay a shop, you could always disconnect the exhaust pipe at the manifold and test that way. You may even be able just to pound your fist on the converter and hear the loose pieces in there.
