I found, after many hours over several months, that my zero
throttle/fullthrottle switch had fallen off of the bottom of the throttle body
on my 85 1.9.
I had no ideal that it was there in the first place, as the manual makes very
little mention of it unless you know to look.
1) What a stupid place to put that switch. VW hasn't done that on any other
model I've owned. Every other one puts them on the top in plain sight.
2) It appears to have been glued in place, and was mounted on the bottom of
the throttle body. Dumb dumb dumb. Inevitable failure as the glue aged, just
when was the question. I Tyrap'd (TM) it in place. It ain't going nowhere
again.
What were they thinking?
It's running the best it has since I bought it in 2000. And it's been in 2 of
the supposeed best VW shops in Minneapolis 4 or 5 times and they never noticed.
I can't blame them, since these are fairly rare vehicles that don't show up
much anymore, and didn't often even when new.
