I did try pin 8 again, and I still get code 1. Cruise control works fine. The car runs worst when it is cold--no power and wierd shift points--then it runs fairly well when warm. Next week I'll let you know how it runs with a new coil and spark plugs, and I ordered 3 new spark plug boots, too, just in case. The symptoms are very similar to the last time a coil went bad. (I also need to do some research into which wiring harness the dealer changed.)
