Well, tonight went to drive it somewhere. Ive driven it >100 miles since changing the battery and clamps,and it never died or tried to, but MOST of that was high speed driving evaluating if the acceleration problem was there.

Sitting at a stoplights for a while, after it had been operating for ~20 min, the check transmission and airbag lights came on, battery voltage pegged out >16, and light squeal sound started. I shifted to Neutral and revved the accel, the squeal gets louder, When I tried to drive forward in Drive, the vehicle didnt move very fast,like it was in wrong gear, So I manually shift to 2 to start off, and start to drive, and it starts dieing. It dies. I shift to P and restart, and it dies again. I start it again, and everything is fine, works normally, squeal is gone, and we drive away. Later when I push accel hard, it starts the problem there again.

Seems like maybe the alternator almost seizes sometimes or something? Since the AC seized up, I took the belt off there and the only things left to squeal are the alt and ps.
