it is normal for the idle to jump to 2k RPMs when its cold,..its just the ECU warming up the motor,....as for the idling jumping,...run a search for something like "erratic idle" or something like that,...i think its the fast idle but im not sure,..the fast idle may just need to be tighten

 

i would clean the IACV if you havent done so already. The you can check the FITV, which is under the Throttle body,( some models dont have FITV).

 

before you go and buy anything, **** with your idle screw, i had the same problem and the idle screw was just a lil out of place.

 

Get a new IAC Valve from Honda.

i dont think he should do that,..he didnt say anything about throwing a code for the iACV,...he might just need to clean the screen
