Driving FaSSt

Tranny is good i would assume.. Doesnt slip under load, shifts hard, goes thro gears just fine, shifts all gears hard and firm at wot.

But when i come to a complete stop or slow roll driving around town. (stoplights, turning onto streets, pulling into parking lots, etc) as i give it gas it hesitates and then power comes on after maybe a 1 1/2 seconds.. partail throttle and normal DD driving

Any input or ideas..

TPS Sensor?
Convertor itself?

any help will be very appreciated
