[V8] ' 93 V8Q - Accelarator/throttle shaft

[Ed Kellock]

That box is/contains the kickdown switch.  The thing is pretty convoluted
and clearly, prone to failure.  I pulled the one out of my parts car and
disectted it and have determined how it seems to fail most commonly.  I've
cobbled up a really ugly fix which I have not tested yet.  It at least one
case, I was able to trick/fix the thing to work by tying the cable (in the
engine compartment) into a position that lines up the inner workings at the
fire wall.  I'm going to look at it again before I try to describe it, but
there is a stout sprint in there.

Sadly, the dealer will only happily sell you a new cable end to end, box
included, one part for somewhere around, probably north of a hundred bux.  I
did buy a new one just to see how the hell it's assembled.  I managed to not
break it doing so and then installed it.

Thanks for the response. I already fixed that part(1/2" cable ferrule) of
the issue with the accelerator cable. This issue appears to be with the
return spring on the throttle shaft and/or the little 'box' thing that sits
in the firewall that the cable come through. No-one seems to know what this
box is or does but mine is detached from the retainer and there is a spring
inside the box. Guess will have to consult the 'dealer' on this.

  I found a problem that resulted in similar symptoms, but had it's origin
at the cable end in the firewall, where it connects with the pedal. The 1
1/2" cable ferrule left it's seat and it's end was pressing against the
holder. This increased the housing length and caused the cable to come under
tension in it's housing.
   The result was the accelerator stayed on when there was no pressure on
the pedal. Easy to look up above the pedal and see if the ferrule is out of
place.  Bob in Delaware. 
    Anyone near me? My '93 may be evicted by the County and need a place to
be... 
This shouldn't happen to a '93.
