it could be your tps or 02 sensor as i had a similair problem.

numpty, more than likely be a ecu related problem, which could be traced back to the tps sensor (throtle posistion sensor,) get it looked at by a auto sparky, dont take it to a auto tranny guy, it's defently electrical, not a auto problem at all, sensor related

it's a bit hard to say anymore than that, it could be anything, hard to tell without looking at it
