TRANSMISSION - TRANSAXLE - ATX - SHIFT CONCERNS - THROTTLE VALVE (TV) LINKAGE ADJUSTMENT PROCEDURE


FORD 1984 TEMPO - 2.3L HSC ENGINE

LINCOLN-MERCURY 1984 TOPAZ - 2.3L HSC ENGINE

When servicing a shift concern, or when an adjustment of the curb idle speed to the specification indicated on the Emission Control Decal results in an RPM increase/decrease of more than 100 RPM, the transaxle throttle valve linkage must be checked and readjusted if necessary.

The following is the service procedure for throttle valve (TV) linkage adjustment of 2.3L HSC engines:

The TV control linkage must be adjusted at the TV control rod assembly sliding trunnion block using the following procedure:

1. Operate engine until normal operating temperature is reached and all accessories are off. Assure that the hot engine curb idle speed is to specification. Refer to the Engine/Emissions Diagnosis manual.

NOTE: The linkage cannot be properly set if the throttle lever is allowed to be on the choke fast idle cam.

CAUTION: THE FOLLOWING STEPS INVOLVE WORKING IN PROXIMITY TO THE EGR SYSTEM. CARE MUST BE TAKEN TO AVOID CONTACT WITH HOT PARTS.

2. Loosen the bolt on the sliding trunnion block on the TV control rod assembly one turn minimum.

Remove any corrosion from the control rod and free-up the trunnion block so that it slides freely on the control rod.

Figure 14:

3. With the engine idling in Park, rotate the transaxle TV control lever up using one finger and a light force, 4.5 N (approximately 1 pound), to ensure that the TV control lever is against its internal idle stop. Without relaxing the force on the TV control lever, tighten the bolt on the trunnion block (torque specification 7-11 ft.lbs. or 10-15 N-m). Refer to Figure 14.
