When i take off going slow 0-5 mph it is real rough. It bounces a lot when going that slow.

check the tps sensor and the fuel filter, if you put the pedal down at a start to about halfway does it accerlate just fine? how about crusing at highway speeds does the problem only happen in the low accelerator pedal positions.

check for TPS voltage with the pedal at closed throttle and then go steadly up in pressure, is it erratic in the begining and smoother after it gets past half throttle or stay the same throughout?

could be a minor vaccum leak
