Buck / Hesitation???

[silvermelon19]

My 93 just recently started to have a hesitation to it when i give it some gas. As if the truck doest want to go at first, then as i give it more gas it will kick in with no problem. I refer to it as my truck "bucking" Just got a tune up on it last year and just clean the Mass Air. The only thing i can think of is that one of the plugs might have failed? Any ideals???

**Worn out plug wires can do that too.** I suggest you search for the terms "hesitation" and "buck" for more detailed info and other possible causes.
