Surprisingly the PO took really good care of basic maintenance. At least the best on any 30yr old car I've purchased before. Plugs, wires, cap, and rotor were correct Bosch pieces in good shape. Had a recently replaced OE air filter. And oil was changed back in July, only driven a few hundred miles since.

I'm going to check the following things:

Idle control valve
Cold start injector
Duty cycle
O2 sensor
