[200q20v] I'M STILL %!#&* STALLING!!!

I have a bad bypass valve sitting on my shelf that passes "inspection". I'll
be darned if I can make it leak with either vacuum or pressure, yet
replacing it cured the stalling problem on my car. I was really curiuos as
to how that bouncing speedo was causing the stalling problem as even the
tech bulletin said for 1990 only. I can understand and sympathize with your
dis-satisfaction with the dealer. Perhaps the dealer can put your old
circuit board back in and refund your money. I suspect that just sticking
your old board back in will leave the speedo working.

When I had a low boost problem, after many hours of dealer ($$$) trouble
shooting, they decided it had to be the waste gate - cost over $900.
Luckily, Ned Ritchie stumbled on the fact that the Waste Gate Frequency
Valve could cause the problem, and even though mine tested within specs, $40
later I had boost again. I believe it was also Ned that found the stalling
problem being cured by the bypass valve. This was right after lister Peter
H. had spent major $$$$ replacing darn near everything else under the hood
trying to fix his stalling problem. These lists have been invaluable for
many people and have saved fellow listers major $$$$. My local dealership
has worked on maybe 5 91 200s and has never heard of the WGFV or the bypass
valve going bad. I'd bet there are some 200's around the area only seeing
1.3-1.4 bar boost that don't know know they have a problem.
