Group:� � 24
Number:�� 92-01
Date:� �� February 29, 1992
Subject:� Vanagon Intermittent Misfire
Model(s): All Vanagon Digifant Fuel Injection Engines

CONDITION
After driving for 1/2 to 2 hours at a constant speed, vehicle
experiences lack of power, cuts-out or stalls, often accompanied
by
bucking or jerking of the vehicle.
In ALL cases, the vehicle will restart immediately. � This symptom
may
not reoccur for several weeks/months.� Inspection by the dealer
results
in nothing conclusive.

Some airflow meters may experience a vibration resonance of the
metering potentiometer wiper during extended constant driving.
This
resonance causes the airflow meter to supply an intermittent
signal
to the Digifant ECU. � The ECU will then default to a "no-load"
condition
and reduce the injection time.

SERVICE
Harness, Part No. 025 906 302A, is available to resolve this
condition.
