On a cold start my rover jumps up to about 2000rpm and it won't go down until I've put it in gear even then it hangs out just above 1000rpm and at a stop light the rpm's will rev up causing my truck to jump. Whats the deal?

my 98 disco has been doing the same for about two months now. I made a post about it on the old discoweb and some people said to adjust the throttle positioning sensor. I didn't end up doing anything since it revs like normal when in gear (it only revs high in park and neutral when the engine is cold). My disco hasn't died yet so I have just ignored it.

Cool, I'll Check the TPS, I also read some things in other post about cleaning the stepper motor (wherever that is), So I plan on checking that out this weekend.
