Question
When I come to a stop, or slow to a speed bump or even try to do a u-turn, the engine slows to a low idle and sometimes stalls. Someone said it may be the throttle body being sludgy. Is this the only thing that might be wrong? I was also told it was the battery not holding a charge(orginal), so I replaced it and it still happens.

Answer
John,
  I am NOT qualified to answer this question but when I joined this group, I vowed to offer any assistance I can. I'm a Parts Specialist, NOT a Tech but here are my thoughts...
  The problem you are having seems to surround the computer and all the input it is getting. It could be an Idle Air Control Motor (IAC), the Throttle Position Sensor (TPS) or any number of other related sensors. Since the engine had died, the "Check Engine" light has come on, correct? Have you had anyone "scan" the computer for error codes? Something else it could be is the "lock-up" torque converter not "unlocking" at a slow speed. You really need to have the computer scanned to see what error codes are stored in it. I know some parts stores such as O'Reilly has a scan tool you can use to pull the codes from the computer. I don't know what is in your neighborhood.
  I know this doesn't help much but with the information you have given, these are the things I would check. I hope it gives you a little direction. Again, I'm not a Tech, I just push parts. Good luck..
