97 GTX Gauges

[seadoorookie]

My digital gauge on my 97 GTX reads low oil when the tank is full, high temp before I even start it and the tach reads 5000 rpm at idle. Everything else on the digital gauge doesn't seem to work at all. Both analog gauges(tach and speedo) work fine and the machine seems to run fine ~55mph@6800 rpm. What would cause the digital gauge to go haywire??
