Gary, just wondering if you had any luck fixing your issue or are you still unhooking the battery everytime. I have not driven mine in about 3 weeks going through definite withdraw.
Mike, I am the worlds worst at taking a car back to a dealership. I avoid it as long as I can (1) because I really don't have the time (2) they usually futz something else up while they have it and (3) they usually don't have a clue what's wrong so they throw a 'hale Mary' at it and lie to you about what they did. That being said, I have not been able to duplicate the event again. We drove the car to the mountains a couple of weeks ago (150+ mile round trip) without incident. I waited until I got almost home before I tried turning the A/C on. And I have tried unsuccessfully a couple of other times to make the tach futz up, each time without success. WHat I "think" happened is, I left the A/C on when I turned off the car and either that buggered the dash software or it did it when I tried to start the car again. Apparently the ECU is sensitive to anything that disrupts electrical flow, as when something is drawing current . That is just my theory, but it seems to fit.
We drive the car as often as possible. I take it to work at least once a week and we usually take it out on the weekends if we go out to eat or to a movie. I love to drive it and with the new found power, I catch a lot of muscle cars sleeping at stop lights.
Thursdays are usually bike night for us, but maybe all of us locals can get together and do the Thursday night car show (Let's Talk Cars) in High Point or the Friday night gathering at the Sonic in G'boro?
