Gauge Cluster Failure.

[At-Least-It's-An-Evo]

I thought I already told you that there's a oil pressure sensor plug thing that is probably hanging from the bottom of the car right now. Just look for something hanging and plug it back onto the gold round thing that its suppose to be hooked upto. It usually has a tendency to fall off from launches and stuff. The coolant one, check if that's plugged in tightly at the thermostat housing.
