I don't know if anyone else has catloged this before, but it should be helpful.

One of my friends is an engineer at Honda and he told me that at least on Honda vehicles you should be able to get better mileage by turning the key to "ACC" prior to engine start-up for 1-2 minutes. The reason being that in this state, there are element heaters on some of the wide and narrow band fuel mixture sensors that are activated. Then, when you do do turn on the engine and start driving these sensors should be able to effectively adjust the fuel/air ratio.

I don't know how far back this tip works for Hondas, or if it will work for other vehicles.

Who will commit to try it and see if it makes a difference?
