OK. The other night I started the car and immediately the speedo went to 150 and the tach all the way to 9000 rpm and then they went back to zero, then the theft light kept blinking so I turned off the car restarted it, and its fine. Today it wouldnt even crank, then after the 3rd try it cranked and started and the gauges did the same thing. Then .later in the day the car would start until the 10th try or so, the guages did it again and the a/c didnt work. Then I turned it off and it all works fine again. Whats up?
