When the car is ideling when it's warm, it idles steady, but a little low (500 rpms). I know i just need to adjust the idle screw for that. My real concern is that when I let off the gas, or clutch coming into a stop, the rpms go a little below idle and then back up to idle rpms and hold steady. Is it normal for the rpms to drop a little below idle and then come back up when you let off the gas? The only reason that it's a problem is because when your idle rpm is abotu 500 and it goes below that, it gets a little rough. Also, what rpm is the desired idle speed? 750?

Why does everyone think you should adjust the idle screw first?
Engine idle speed changes for a reason. The idle screw is not adjusting itself. Instead of trying to cover up the problem you should always try and figure out WTF is really causing it.
Poor idle can be caused by a number of things. In order:
Plugs
Cap/Rotor
Wires
EGR valve
EGR port in manifold
IACV dirty
TB dirty
Dirty injectors
Bent valves
There is plenty of info on each of these on the board.

If it seems to idle better in cold weather, does that give any info?

I guess because turning the idle screw is cheaper then replacing some of those parts. Yea its not properly fixing the problem, but I know i don't have money to replace a whole bunch of stuff everytime the car hic-ups. And i suppose o could test all those compontents too, but thats a lot of work and most people do not know how to test spark plug wires for example.
The cold weather issue could be a bunch of things. Hard to say without trying some of the things in that list first. Air is more dense so that could be a restriction involving the idle controls- idle setting (if changed), IACV dirty, TB...
I can understand not spending money to fix stuff but most of the stuff on that list is not that expensive. You can abuse the car and let stuff go to crap but it will just cost you more later. If you are too poor to afford plugs/cap/rotor/wires and you drive a Prelude then you should perhaps consider selling it and getting something more economical.

Um... that doesn't make too much sense. I mean... **** is going to go wrong on any car. With that many moving parts, how can it not? So maintenance cannot be a factor in the economical ease of a car. That being said, I cannot stand to drive something that is horrible slow, and 24mpg is not bad for something sporty in my opinion.
But again thanks for the valuable info (minus the rude remark)
Edit: and Honda's are generally relatively easy on maintenance.

Holy back from the dead thread, Batman. Nice, but not entirely accurate for the H22. See my notes above for more information on more common causes of idle (unless you recently swapped a motor, manifold, TB, or have already addressed the issues I list). Bad plugs are the #1 cause I see for a poor idle. Then the dist. cap/rotor, then... see my list.
Well even if you just add thicker oil such as 10w-40 you cause the idle to sink when its hot. I am saying if its idling fine then just turn the screw up a bit. If its missfiring or worse, then yea look at all that stuff on the list.
idle screw is on the upper left with the throttle front facing you. its a big flat screw you can't miss it.
And as for the rpm sinking after a rev. Yes thats normal too. its how EFI engines work. Wehn you let off the throttle completely, it shuts off the fuel injectors to save fuel till it gets to a certain point (low idle rpm) then turns them back on again so the car will idle. That rpm sink is just ecu being a bit slow at turning on the injectors again.
