Default Rough idle on warm startup

This has probably been covered plenty of times already, but I have a warm startup issue. It happens pretty regularly (at least every second warm start). What's happening is that when the car has been running and then has been turned off for a little while, I start it up again with the engine still warm and it misfires until I blip the gas a time or two, and then it's just fine. No other running issues. Excess fuel? Vapor lock?

Sorry but I have to ask about the simple things first.

No stored codes, tune up items related to ign system are up to date (cap, rotor, plugs, inspect wires)?

No, you're fine. Cap, rotor, wires and plugs are all new. The only stored code is the P0420 (catalytic converter system).

Humm, nothing reall comes to mind as a "known/likely" issue on a 6th gen four cyl

I could "guess" at a hundred things but that would help anything but to empty your bank account......
