cw_45 -> Sticky throttle (6/16/2008 1:25:30 PM)
|
I have a ''90 S10 Blazer. Does anybody know if the soft metal cover pressed into the throttle body casting, opposite the steel stop that protrudes and limits how far the shaft the butterflies are mounted on rotates, is actually a cover for the adjustment? These parts are all on the linkage side of the trottle body at the spring. Of course my book doesn''''t break down the throttle body in enough detail to make a good guess. Thanks.

PS: From my answer below, the cover blocks access to the idle adjust screw. Pried it out with a scribe and gave the screw about a 1/4 turn and this kept the butterflies from jamming. Don''t know if where on the throttle stop or wear on the end of the idle adjustment causes this, but they sure were jamming themselves into the side of the TB
