Weird idle problem
I know everyone has an idle problem, and I've searched, but I couldn't find anyone with exactly the same problem I have.
Sometimes after I come to a stop after a long ride, the engine will dip down to ~300 RPMs, get rough, and then go back up to 700. I found a way to replicate the problem though - if I rev the engine to 5k+, then let off, it goes down to 300 for a few seconds (gets rough), then back up to 700.
Anyone have an educated guess what my problem might be?

Re: Weird idle problem (Aphelion)
you can check the timing or on the throttle body there is a air fuel adjusting screw get the manuel for the car and it will tell you how to adjust and fix it pretty good
Kip if I get it fixed, I'll let you know how I did it :]

you can check the timing but whatever you do don't touch the idle screw on the tb cause that's not your problem

Re: (IC33)
The IAC could be dirty , take it off and check the screen in it , Don't go messing with ur idle screw on the TB if u don't have to ... its not a air/fuel adjustment,, it is preset from the factory and if no one has ever messed with it u should leave it alone... it is there to set ur idle.......... souns to me like the iac just might be dirty...check it out

Re: (ReDHaTcHy97)
i had the exact same simptoms... after a rolling road ( for other reasons ) i found my idle problem to be the lambda sensor in the exaust, giving false O2 readings to the ecu
a qwick scrub with steel wool got it going again.. but i should realy recomend you replace it. in the uk there about £75 but u could get a non-honda aproved part for less.
