The '86 5k does not have a mass airflow sensor. It simply has a
charge air temperature sensor in the intake plenum that the com-
puter uses to determine the ignition timing. The airflow is sensed
by the same circular plate in the fuel metering box that everyone
with a Bosch K- or KE-Jetronic (CIS) has. Any leaks after that
point will screw up the measurement, and thus the mixture.
