I took the car to a mechanic and he did the following to fix the problems stated in my original post.

1. changed the brake sensors and brake lines
2. Just kept tightening the bolt until it "locked" - impact wrench
3. Changed the 2 bulbs and socket
4. New ground wire did the trick. RPM and clock now works. (economy guage still not working - got to try to find the vaccum leak --- can someone give me advice on this problem?)


Just wanted to share my experience....maybe it'll help someone save $$$$ if they are havin simlar problems.
