the blower motor for the ac/heater requires quite a bit of power to run and it will make your engine rpms change. if you notice also your engine will change speed if you turn your headlights on. same thing

Actually it's just if you turn the AC on and off. The AC compressor is connected to the crank by a pulley, which steals horsepower, which is why many people remove their AC. I think the fans are just little electric fans.

ORIGINAL: sacicons

unplug the o2 sensor. it will set off a CEL and put it in open loop, like it is when its cold. but it kills VTEC (as it does when its cold) as well as killing the fuel economy. also, most of that power comes from the less heat in the engine bay, making lower intake temps.
Taking off the 02 sensor isn't thte most practical idea. I did it to one of our cars and we went from 19mpg to 6 mpg. It kills your gas mileage.
