I had an 88 Regal once that was doing something that sounds similar and it turned out to be the cat restricting flow and causing back pressure at high throttle/RPM.
Given the discussion so far, I assume that you are way beyond this. Just a thought though.
Thanks lakeq45, I am a bit past that, but I appreciate the input nonetheless.
I actually re-read Jesda's post from 2004 and I'm beginning to lean towards just putting a new MAF in and see what it does. This is friggin maddening and the temps in PHX are already in triple digits. Even with A/C in the garage, wrenching is no joy.
I'm going to try Wes' fp ground bypass just for grins and giggles but if that doesn't make a difference, I think I'm giving Joe a call tomorrow.
Thanks for the two cents guys... I hope to get this resolved and the thread will be worth something to someone else down the line.
