Throttle Body: Adjustments

Fig. 72 Idle Speed Screw:

Synchronize the throttle bodies if there is a gap between the adjustment screw and the linkage lever. Also, synchronize the throttle bodies after removing and installing the throttle bodies.

1. Install 0.004 inch feeler gauge between the idle speed screw and throttle lever on the right throttle body (Fig. 72).

Fig. 73 Adjustment Screw:

2. Loosen the adjustment screw locknut on the synchronization shaft (Fig. 73).
3. Turn adjustment screw until it just contacts the lever on the synchronization shaft. Tighten the locknut to 4 Nm (36 in. lbs.) torque.
4. Check clearance between the throttle lever and the idle speed screw. The 0.004 inch feeler gauge should drag when removed. Also, a 0.006 inch feeler gauge should not fit between throttle lever and idle speed screw.
