I would replace the instrument cluster first. They are really and regular problem. It took me about 20 minutes to replace. At least you can see what your guage's show what your engine doing. Hot,cold,oil pressure, and voltage can may give you a hint to where to search first.

right , and if there's shorts/problems in the cluster voltage can find different paths from all different sources and the computer won't know what's going on
