CHECK THE THROTTLE POSITION SENSOR VOLTAGE:
Turn the ignition switch to
the “ON” position but do not start the engine. Using a digital volt/ohmmeter, measure
the voltage between the Dark Green/Light Green wire and the Black wire. Be sure the
voltage is between 0.8v and 1.0v. This voltage can be adjusted by loosening the two
screws and slightly rotating the throttle position sensor. If necessary, elongate the
mounting holes on the throttle position sensor to obtain this specification. (See Photo
#6).
Note: For optimum performance on 1986-1988 vehicles equipped with speed-
density system, we strongly recommend mass-airflow conversion. Kits
are available from Ford performance parts and other aftermarket outfits.
