The Lambda O2 sensor is perhaps THE most important sensor in the late
Vanagon injection. After as all of the other inputs are considered
(temperature, air flow, etc) the logic program is heavily influenced by
the Lambda's evaluation of the "final condition" of the effluent.

Without it, the ECU can rely only on its "limp home" program, which is
characteristically rich, and very poorly managed. Buy an O2 sensor,
ASAP.
