Actually, the idle was fine prior to the misguided attempt to lower the idle speed. The attempt was a response to a harsh engagement of the transmission from Park to Drive and more noticeably, Reverse. This was attempted with the idea that a lower idle would produce a smaller "clunk" during engagement. The replacement of the flex discs has remedied this problem and now I would like to simply return the idle to it's pre-tampered state. Thank you for your response. William
