Check the throttle plate is closing, it may be stiff or clogged up with shit. Remove the intake pipe at the throttle body and give it a good spray with some brake cleaner and wipe it out.
tps mate, i had similar symtoms, and found the tps was not giving correct readings, now tih new sensor, it is fine.
worth checking ys tps matey, id presume car is stock???
if so heres tutorial on setting tps up.
as far as i know, the TPS on the automatic throttle body is different to the manual one so the connector wouldnt fit so maybe theres a manual one on there already for it to fit the loom?
