It's finally cooling off in Vegas, and I'm sick of trying to figure out why the black wagon is still misfiring after basically rebuilding the ignition system, so it's time for George to ride again! Gonna get an alignment soon.
EDIT: Someone at the A-body board mentioned injectors. At this point, I'm leaning toward injectors, but since testing that requires pulling the upper intake, I'm not going to do that just yet. I plan to change over to the non-A-body-style throttle body, throttle position sensor, and mass air flow sensor, and get another '97 W-body PCM from Milzy. There's a '98 Grand Am at the yard up the street that's not been picked apart yet, so I'll grab the upper, TB, TPS, cruise module, throttle cables, and MAF from that. Then I'll probably just slam in some new injectors as a matter of course.
I know I said when I bought this car that I didn't plan to do any modifications, but I consider the MAF swap a necessity at this point. It's becoming more and more difficult to acquire the Buick-style MAF, since it was only used on a few cars for a few years. Whereas the newer style was used on many more cars for many more years, so it's both more plentiful at the yard and easier to buy new if I need to. The factory TPS doesn't seem to be calibrated correctly either, reporting 66% at actual WOT. And yes, "while I'm in there", why not just upgrade to the 2000+ top end, right? No time, money, or motivation for that.
