Check all of your air lines - I reckon that one of them is split or leaking. It could also be a temperature sensor fault. Unplug the temp sensor and if the revs stay as they were it's that sensor if they climb higher it's another fault. You may also need to service the car a new air filter & plugs could be a simple solution. The T series engine does not like short journeys and cakes up inside quickly - stick in some redex and go for a long drive. The mems unit sets the timing based on an average of the last 200 miles - so the fault may take a while to clear up even after the cause is fixed but you will notice a small improvement immediately.

I've got a rover 420 gsi tourer, 1996. At the moment she has got a problem with the revs. When you start her up the rev counter constantly fluctuates from 1000 - 2000 rpm while the car is idle. Any idea what the fault is?
