I have a 85 Mustang 5.0 Convertible, and this morning, when I fired it up to go to work, it seemed to be running okay, but the stereo illumination was flashing on and off and the rpm guage was jumping around 6k rpm(even though the engine was at a mild idle). It did this for about 30 seconds, then all just went black. No power at all, no matter what I did with the key in the ignition. Then, when I decided to get out and push the car back into the garage and take my other car, the lights came back on and everything worked normally. I was able to start it back up and go to work, although with a certain amount of nervousness, without incident. Is there such a thing as an automotive exorcist I could call to remove this demon playing with my mind?
ANY input to calm my mind and help me know what to check on the car would be appreciated. My peace of mind is at stake!
