Cruise Control Cable
WARNING: This page is about a different car, the 1992 Subaru SVX, 1992 Subaru Legacy, 1991 Subaru Legacy, and 1990 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.
Check clearance between cruise control cable throttle cam and cam stop. SeeFig 1 and Fig 2 . If clearance is not .040" (1 mm), loosen adjusting nuts. Move cable sheath toward or away from throttle cam as necessary to adjust clearance. Moving sheath toward cam increases clearance. Moving sheath away from cam reduces clearance.
