1997 Ford F-150 - Sputters

My truck sputters when I give it gas but idles just fine what do you think the problem is

The problem is that you haven’t told us anything about the truck or much about the problem.

Engine type and size?
Transmission type?
Mileage?
Check engine light on? For how long? Do you have the trouble codes?
Does this happen all the time? When hot? when cold?
When you give it gas, does it “catch” and then accelerate OK after it “catches”

You answer all of these and we’ll try and help.
