Check the water temp sensor (the one for the ecu, not the gauge). 140-160 1974

On D-jet b20's there is a sensor at the front of the head that sends water temp to the ECU. This will make the car run full rich if shorted, I believe.

Thanks to greenteagod.

The sensor at the back of the head is for the gauge. Doesn't affect running.

There are specs for the resistance of this sensor somewhere, If you wnat to test.

If the car has been running rich consistently, the plugs are caked, and it will take some running to clear the carbon from the cylinders.

A busted map sensor will give just radically uneven running.
