I would check the O2 sensor wires. We had a similar issue with our '86
with a 2.1/MT. Turned out the connector at the sensor was allowing water
in. My guess is that it closed the circuit before the sensor and caused
the ECU to think it was running really lean or rich.
I threw some "rescue tape <http://www.rescuetape.com/>" on it and continued
on. It held well but it was at the back end of the sensor plug so there
was plenty of air flow to not melt it.
