Check the tranny fluid level when warm. Low fluid can cause the TC to stay in lockup.

IAT solenoid probably needs cleaned. Not a hard job.

The IAC is located on the left side of the throttle body (left side when looking at it from the driver's seat). You will see two items with wires attached to them. The top one is the Throttle Positioner. The bottom one is the IAC.
Unplug the wiring harness from the IAC. Remove the two Torx screws and carefully pull it straight out of the throttle body. Use Throttle Body and Intake Cleaner, which can be found at your local auto parts store. Spray the stuff on there, let it sit a while, spray some more, and carefully wipe it with a paper towel. Repeat until it is clean, being especially careful not to bend the plunger shaft. Also clean the bore that the IAC goes into. Remove the intake tube and clean out the entire throttle body with the cleaner. Put everything back together.
I did the above procedure, and it smoothed the idle out quite a bit, although it's still a little rough at low idle (when it drops to just over 500 RPM).
