Only guessing Steve as not familiar with your set up -
Have you checked all of the vacuum hoses?
I know i had a similar problem on a 730 which was caused by a failing vacuum hose from under the inlet manifold to the fuel regulator.
Drive a BMW and you will have a smile on your face every time (and- drive twice as far as you need to !!)
