DIC Fuel Problems
The Fuel part of the DIC on my 97 Coupe is going crazy. It keeps giving me all kinds of numbers. It go's from Low range to 325 miles and all over. won't stay anywhere and the Instant MIleage is moving all over, so is the average. Everthing else work ok. What do I need to replace? What is making it do this?

This is a common problem...
Usually the cause is a dirty fuel sending unit.
If that is the problem a few tankfulls of top tier fuel www.toptierfuel.com should help. If you want quicker results posts report that Chevron Techron additive added to a couple tankfulls should sort it out. In the same vein others use Chemtool B12 or BK 44
The Chevron and Chemtool are readily available at autoparts stores... even Walmart... the BK is more of a specialty product used at import delaerships.
If it is not this them it could be corrosion on the ground to the sending unit. there are posts that show where to find it ans what it looks like.
Finally the sending unit might have to be replaced.
Start simple and cheap and add some techron to the tank a fill up only with top tier fuels.
