Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) High Idle speed when car is moving

Hi All

My 2013 plus 4 (with the Duratec 2 litre) has strange engine idling. When the car is rolling (but with the clutch depressed) the idle is about 1500 rpm. When the car stops it lingers a second or two then goes down to around 1000 rpm.

Any ideas on this behaviour? Seems odd to me; it means that once the car is moving it wants to go a about 20mph in second!
