High idle 2.7 CRD

Strange problem on my 2003 2.7 CRD, mileage 104K. Idle is normally at 700 RPM and idles smoothly with no surging. If I blip the throttle with the trans in park the idle sticks at about 1200 RPM and drops very gradually. If I drop it into drive it drops instantly to 700. It's difficult to tell but I think it happens very rarely when driving.
CEL light not on and only code is P0836. I think that's something to do with FWD which I have never used.
Could this be the TPS? Does it have a TPS? Does something need cleaning or replacing? If so what and where is it
All help much appreciated.

If at first you don't succeed, find somebody who knows what he's doing.
