yeah i dont think it sounds like a clutch. working at a dealership, ive driven a few cars that i know have bad clutches and havent ran into this. all ive ran into was when you let the pedal out, the car just doesnt accelerate and revs go up. this is just my experience though and wouldnt rule out the clutch. i personally have a bucking prob like you do when mine is at low rpm's and then once it passes in each gear and warms up, is fine. i feel mine is a just a fuel pump or some kind of delivery prob.. try letting your car warm for about 10 min before you take off next and see if it runs better. maybe bad injectors? bad pump? clean maf. run through some injector cleaner. idk man, just try all the cheaper stuff before you take it to a shop cuz like all others said, its not too cheap.
