and I've just read an article from Motor magazine to support my point: "dragging intake past that almost-shut butterfly (cruising at low rpm) creates a partial vacuum in the intake tract and the engine has to work to overcome this vacuum and drag the atmosphere into it's lungs, resulting in partial cylinder fill and therefore lower efficiency" ('Variable Cylinder Management' by David Morley, Motor, October 2008)
I'm going to give it a go and reset the ECU by disconnecting the negative terminal for a good few minutes, though my mate just asked what about the alarm?...
