So I have always wondered this and I figured I should just ask.

Every Honda I have owned always drops revs at idle when accessories are turned on--especifically when there is more electrical strain involved (ie: headlights, heater, etc).

Now, I was wondering if this has to do with the fact that every Honda I have owned has been used (the "newest one" I have ever owned is my current 00 EK) and because of that, the alternators may have been worn. I have never had an alternator die on me in a Honda though, so I never got to see what it was like having a new one with these cars.

So, my question is, are Honda's this way even when brand new? Or is it worn electronics that lead to this.

I am just wondering because every German car I have owned didn't have this issue. Even my old BMW 2002's.

 

Huh? none of the cars ive been in or cars ive owned have ever done this even when the alternators took a ****.

 

Mine does in cold weather.
Cold as in -20 degrees Cel. +

Once the engine is warm it's all good.

 

Interesting. For me, it's always the heater that makes the revs drop...

 

if anything my car idles lowest when nothing is on but when i turn the heater or headlights on my rpms go up

 

The only Honda I have had that does something similar is my CRX. But it has an OBD0 B16a engine in it.
