I believe I have success. I removed (much easier than checking in place) and checked the TPS and checked the smoothness of the resistance change. I first used a digital meter and didn't like the way that worked and thought I saw a rough spot anyway. I then used an old analog meter and everything worked good. I reinstalled that and checked the MAF elements. That looked good so I put everything back together. Something I did must have fixed the problem because now I have no hesitation. Even the transmission seems to shift better (might be my imagination though). For a car with just over 200,000 miles she runs really good now.
Thanks to everyone for their suggestions.
