Power loss with hot humid weather?
Anyone else having problems with power when its 90-100+ degrees outside, my wife told me her 8 is really running sluggish when its hot out, at night most of the power comes back, so I kinda threw it out as A/C bogging the car down.

All air-breathing internal combustion engines do poorer in hot humid air. The scale of oxygen content (density) goodness, best - worst:
Cold Dry Air
Cold Humid Air
Hot Dry Air
Hot Humid Air
It's a Boyle's Law of Gases thing.
Running the A/C of course puts extra load on the engine, diminishing power, as well.

Huey is correct and right - the denser the air the better. It's the same as the story about it being better to fill your tank when the ground is cold as there's more liquid and not as much fumes going into your tank compared to a hot day.
