    how do i get the butterfly shafts out? the injector pod is pretty straight forward, but the base is not. i've got it down to the throttle linkage and the part the tps fits over. what's next.

    anyone got an exploded view of the tbi or something?
    thanks fellas

    well, i may have screwed the pooch on this one. i started to release the return spring. and i can't get it off or get it back taught. then i tried to unscrew the butterfly screws not realizing they are soldered on the back side and sheared one off. i may be able to solder the hole up. but in my rebuild kit from napa, there are two rods that look like shafts. any one else?

    I don't have the rbuild kit but Iknow some kit contain the shafts because they wear.
    usually it's smashed not soldered but I guess the TBI's are soldered?
    Anyway if you have the shafts and the screws, new, then remove those screws by grinding or something and replace the shafts.
