I own a 99 Honda Civic. At the moment, I just recently noticed it after a friend pointed it out, but it seems that while my car is on and idle (brake or handbrake on), the car is sitting on 500 revs. My friend pointed out that when the car is idle, it should be sitting at 1000.
Is that true, and if it is meant to be sitting on 1000, how do I fix this?
500 seems a little low.. 600-700 I thought is normal
Is the idle also fluctuations (going up and down between revs)? Or just sittin flat at 500.. if you'd like to advance the timing a little better.. then you can unbolt the distributor and move it a little clockwise or anti clockwise til you hear the engine idle you need and also have a friend looking at the tacho
gio if you're gonna flame about searching at least find the magical thread you speak of
in other news, on cold the iacv usually lets more air in to help it get up to operating temp quicker
as it reaches operating temp it'll settle down a few hundred
like i said run out an check under your bonnet before adjusting anything, may or may not be within range for all you know
