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.
