I have a 92 toy 4x4 22re 5 speed and I rebuit it and all is fine except I have a high idle 11-1200rpm. I had throttle body checked at dealer and i adjusted the idle screw all the way in & no change, I adjusted it out & it started hunting probably around 1300 like it should. I did notice when I hit the brake it starts hunting. I think that means I have a vacuum leak. Any help would be appreciated.
