oo Expy tps changed

I changed my tps switch recently. It seems to have solved many of my problems with tranny shifting. I still have a minor problem on occasion. Any ideas?

Probably a vacuum leak or a goofy IAC.

Any CEL? Have you scanned it for any codes?

Check Engine Lite or Service Engine Soon (SES) or Malfunction Indicator Lamp (MIL)

Idle Air Control valve. It is responsible for controlling idle speed and is a common failure.
