Again, when it rains it pours!!...now bad throttle switch? AGAIN

[L DC]

Call it irony, call it rain, obviously the cause is
rain (H2O)!!

This morning as I'm driving to work on the highway and
just a block away from the toll, the '85 VW QSW (JT
code engine) starts to exhibit the same behavior after
driving under the rain for some 30 minutes.

Car starts to loose power and sputters and I can not
rev engine.

I pulled over, 1/2 block shy of the toll, to fix the
problem: ZIP TIED the WOT switch (the one on top of
the throttle body) and I'm back in business. It's nice
that is a quick and easy fix.

But, what sensor is getting wet or humid that's
causing the culprit?

Car runs very nice and very smooth on non rainy days
and smooth on rainy days with WOT switch ZIP TIED.

Oh, the irony, last time the problem first happened
was also on a rainy Thursday on my way to work on the
same highway a little over a month ago.

Funny thing I told my brother this morning, "I hope
the car doesn't start with its jerkiness since it's
raining."

His response, while laughing was: "Your car is just
like grandpa, he doesn't like to go out in the rain."
 
Thanks in advance.
