Idles rough for a few seconds after warming up and restarting on hot day

I have a 2004 Nisan Xterra 3.3L. Recently it’s been really hot here in Florida. The car runs fine all the time except when I drive it about 10mins in the hottest part of the day and park in a hot parking lot. Then its starts right up but idles rough. After I drive it for a minute or two it goes away and again runs fine. NO error codes being thrown. I’ve cleaned the MAP. My wires and plugs are NGK and around 2 years old. Air filter is brand new. Again this only happens in the above circumstances at all other times there are no issues and it idles so smooth you can barely tell its running.

Suggestions?

I also live in Florida and mine is the opposite! Idle smooth until it warms up, after a long ride it will idle a little rough, I think it's an engine mount though.
