So you replaced the throttle body (not sure what a TBI is...) with a BBA reman and now you're having the same problem again? What was the reason for replacing the TBI in the first place?
I'll tell you what to look for, is throttle body cleaning on the board. I had the same symptoms you have and the problem was the resistor tracks in the throttle body. they get carbon buildup on them and then the computer has a hard time telling EXACTLY where the throttle is at so it will "hunt" up/down (just barely but enough you can feel it).
I chose to clean it myself instead of buy a reman...I can afford alcohol & wipes but not a TB :)
Good luck,
Seth
