My 760 turbo has been developing an annoying habit of suddenly dropping the idle speed from the normal 750 rpm to 450-500 rpm when stopped. This is frequently accompanied by no throttle response (none, nada, zilch etc) for an agonizing 5-10 seconds when trying to resume speed. After the 5-10 seconds a smidge of hesitation is felt and then normal power returns. Usually, once the low idle problem starts it will continue until the ignition is turned off. The no throttle response problem, however, will only occur once or twice during this period. The no throttle respone problem hasn't occurred unless accompanied by the low idle. After the car gets rolling, power and response are normal. Point me in the right direction and I'll report the results. Thanks!!
