This one is for the East Coast guys.  We Left Coasters don't see this
condition often...  Igor or Osman??

Third gear is typically where the car will see the highest boost.  Remember,
the stock boost guage reads low.  1.1 bar may well be 1.2-1.3...

Replace the WOT switch.  They almost always fail.  The continuity test is
far from reliable.  If the WOT has more than 75km or 5 years I'd replace it.
It is only $45 from Linda, and it will save you a bunch of aggravation
tracking down intake air temp sensors and WGFV's.  Try that first.

Yea, I betcha it is an early 1986 w/ no bilevel switch.  I replaced 2 (count
'em, 2) ECC head units til if found one that didn't do what you describe.
Grab one out of a junk yard.  Cheap and easy, just find one that works...

Frankly I'm impressed at your knowledge of the 5ktq.  I only know the little
I do because of ownership.  Keep up the good work...
