So fog...

Cold air is denser and simply increases the amount of O2 in a given volume and the ECU adjusts the ignition/fueling.
It has nothing to do with the moisture content of fog.
Atmospheric presurre does have an effect but only really noticable with large changes in height from sea level.

Hey Sin
It was equally as foggy here last night.

Sorry if its a long post but i looked into this a long time ago:

It gives me ideas for a perfume atomiser behind the induction kit! :-)

On a dyno it can effect power output, I've witnessed it.

Before I start I'll be the first person to say that in the colder weather compared to summer the throttle response seems sharper but actual noticeable power difference is well, debatable.
Today the fog rolled in thick and heavy in the island, between 50 and 150yds of visibility depending on where you are and it's pretty moist. I can feel it breathing in and well, either it's total placebo as a result of fog or I am cracking up but oh my lord I have never seen my rev counter so keen.
Noticeably keener, I have never experience the car accelerate as much as it did from 2nd gear out of VTEC from 20 up towards 45 so quickly. Nothing has changed other than the car got a clean after all this snow etc...maybe it is just repaying the favour
Fog = water vapour = more Oxygen in combustion process etc etc? Yes, no, maybe...shutup Sin_Chase?
