Last night the wife called with car trouble. She went in a store and everything was fine. Came back out and started the car and the CEL was on, the TC light was on, and the the display kept flashing something about the power steering. She tried to move it and the car "bug jumped" as it was moving. I drove in to get her and started the car to see what it was doing. The CEL light was on but nothing else. I decided to drive it home. Everything was good for about 5 miles and then the dash lit up like a Christmas tree. All of the above plus ABS and Security lights. One red light was on and off but it was so quick I couldn't tell what it was. Still drove fine though. Then the Speedometer started jumping all over, but the tach was fine. Still drove fine. When I was almost home and had to speed up and slow down a lot, I noticed some weird shifting. Any ideas where to start?
