What is your idle speed set at? Mine, (M6), idles right around 800rpm, which seems a tad high to me. Of course, I've been wrong before........

Around 800rpm warm and 1000rpm cold. Valve timing overlap and current emissions standards preclude a lower idle speed. It sure is cool when the motor starts the car aswaying at a stoplight. :D :D :D
