Tim,
Good to see that you are still around. Wondered if you were still into the Turbo Buicks or not many times.
On the stock MAF, you may have luck with a reman A1 Cardone unit through Auto Zone. Use your scan tool to determine if it specs within parameters at idle and WOT. You may have to return a few before finding one that is good. I have a spare I got through them. Eventually, all of us stock MAF users will have to go the translator/ LT1 or LS1 MAF route. Good luck!
