Air Bleed Solenoid - Rough Running/Loads Up

83ford21

Article No. 83-4-23


LOADS, RUNS ROUGH, AND POOR FUEL ECONOMY AT ALTITUDE - 2.3L ALTITUDE ENGINE (SEE CALIBRATION LIST)


LIGHT TRUCKS 1983 RANGER

CALIBRATIONS: Altitude calibrations 3-49X, 3-49Y, 3-50X, 3-50Y If one of the subject vehicles/engine calibrations experiences reduced fuel economy, rough running and/or loading, the cause could be the air bleed solenoid. The following diagnostic procedure will identify an electrically or mechanically inoperative solenoid:

Test the solenoid as follows (located on the side of the carburetor):

1. Attach an ohmmeter across the solenoid terminals. The reading should be 40 +/- 2 ohms.
2. Attach an ohmmeter across one terminal and the solenoid can. This reading should show an open circuit.
3. Attach an ohmmeter across the other solenoid terminal and the solenoid can. This reading should show an open circuit.
4. With engine off, disconnect the feedback solenoid from the input wire. Apply a stethoscope or metal rod to the solenoid body and then engage the solenoid from an external 12VDC source and listen (or feel) for a single pulse of the solenoid indicating the solenoid has activated the air bleed valve. If no single pulse is felt or heard, replace the solenoid and gasket and repeat the above test for confirmation of diagnosis.
5. If the results on any of these tests are not indicated, replace the solenoid.
