For a while, when starting-up warm, my M20 has occasionally revved up to about 2.5k for a few seconds and then dropped back to it's normal idle speed.
This evening, it was a b17ch to start from cold - which it isn't usually - and when it did start it went straight to 2.5k and stayed there. I had to get to work, so I drove it like that for about 5 miles (I know, I know......). Then the engine just died and wouldn't start again.
I'm thinking ICV. Anyone got any better ideas??
TIA
Stuart.
