Okay so here's whats happening; if I start the car (96 trans am lt1) in the morning or when it hasn't been runing it starts right up. However oncebit reaches operating temp, it starts HARD. Many cranks, almost to the point of draining the battery. It also jumps up and on in rpms, again, only whenbits warm. The highway is unbearable because of this. It seems almost as if its shifting back and forth between 3 and 4. (4l60e) I thought this was caused by a faulty fuel pressure regulator, but after replacing it with a brand new one, the symptoms have not gone away

You'll have to do some troubleshooting, but have a look at these....

Don't know if it is the same issue, but mine did a lot of what you are describing.
