4.3L hesitation

[GMCTruck]

Hey guys i got a 94 Sonoma 4.3L V6 4x4 5spd.... here is my problem sometimes when i start driving the engine will like start hesitating when i push the accelerator... but then on other days it will seem to be fine and no problems at all... the plugs and wires have been changed, i was thinking it could be the timing b/c the rotor has been replaced b4.... what do u think?... plus it does seem to burn a little oil... cant physically see any leaks or blue smoke... but yet fluid level changes.... lol

I would start by changing your fuel filter - this is an easy and cheap thing to do.
