sounds like a lambada sensor prob matey and your car has gone into safe mode.

get under your car and whip out the metal thing or things sticking out your cat pipe. disconcet the wire and give them a good clean.

see if that helps.

does anyone else think it could be the lambar sensor????

So when your ideling its sitting at 2500rpm?

Id hazard a guess that the throttle body is sticking. Id be tempted to take it off an clean it up.
Have a search on TDC sensors as well

Sucking in air or electrical problem with the TB is my guess.

Do the revs settle if you try and stall it by lifting the clutch?

Good point, have you had the upper inlet of lately? Could be the gasket has gone and hasnt properly sealed the joint up.
