Hi Amarin,

I missed your reply until now.
Thanks for the details, photos, and comments.

Plated through holes are indeed a common failure point on circuit boards and
the worst offenders are under LSI's, no fun to remove to get at the repair.

I found two bad intermittent through holes in my 940 instrument cluster,
and was hard to confirm but easy to fix with a 1" jumper.
This was for the fuel gauge that was busted from day one.
It's a mystery how any through hole connections work reliably with that flex board.

I'm unable to work under the dash yet with with a lame left arm.
Luckily the car is running in it's perfect behavior mode now,
subject to change without notice, conforming to Murphy's Law.
If the engine reverts into "speed limiting" behavior, by seemingly
running on two cylinders, plan A is to unhook the battery for ten minutes
and see if that might reset the ECU.
There's a crazy idea promoted by Micro$oft.
Is there a a procedure to clear ECU memory?
Yes, I suspect the ECU is the likely culprit.

Best regards, Bill
