U'r engine size might help....
Well the heater core might be plug'd, or for some reason the coolants not flowing through the motor/heater core correctly.

The oil sending unit may be bad, broken wires, dirty connections, bad gauge cluster.

The Abs, its hard to tell. How many miles on this 92?
Most likly the wheel speed sensors failing,sometimes.
