My 91 164S 5 spd doesn't stumble, it trips.   I haven't tried to reproduce
the problem because it trips hard, and not on hard acceleration! It feels as
though I've reached the rev limiter, only harsher.  I think it kicks at
about 4500 rpm, but can't be certain. It began by having some starting
troubles, and now doesn't seem to be getting fuel.  It turns and turns and
turns. This just after replacing the transmission.  I'm guessing a bad relay
or sender, something electronic and magical. :(

Thoughts?
