Any CEL codes present? Could be a problem with the IAC (idle air control) valve. When was the last time you cleaned the throttle body? Check this link out.

Check for vacuum leaks, replace that o2 sensor, make sure throttle body is bolted down tight. Also, when you replaced TPS did you reset the system?
What was the reason for replacing TPS?
