Truck Just not running right

[Duner]

It started about a week ago with the truck getting slugish. Not wanting to accerlate. With back fires here and there. But once it starts going it is fine. It is mainly first gear wanting to stall when i am comming off the clutch and then accerlating fine. We replaced the oxgen sencor about 5-6 thousand miles ago. Along with the plugs. So any help will be great thanks

It is a 90 4.0 with an ax15 4x4

how's the clutch? How's the CPS? Fuel Filter?

The clutch is fine changed about a year ago, the cps was changed within the last year. the fuel filter has not been changed but it did get a new fuel pump in may

Why would you not put on a new filter with a new pump change?

Now that i talked to my dad we did change it we work on so many cars round the house that sometime i can"t remember what exactly i did
