I noticed that my 06 CRV, whenever in stop and go traffic, would seem to choke when I brake. RPM drops to about 200-300 but recovers right away. It does not "hunt" for RPMs as is usually described for IAC valve issues. On certain occasions, especially uphill with the AC on, something seems to engage (feels like the aux fan) that suddenly starves the engine of power. I have to put the pedal to the floor to maintain momentum or turn off the AC to get some power back. The engine does not die but is very sluggish. Then after a few seconds, whatever that "engagement" is, releases and all is normal again. Many people say its an IAC issue, but the forums I've read explain different symptoms for dirty IACs. Anyone with similar experiences?

Welcome to the CRVOC forums, Ack459! Have you checked for any vacuum leaks? I would check the IAC and/or the FITV. Also when's the last time you've cleaned the throttle body and butterfly plate? I've cleaned both my 2005 and 2006's throttle body assemblies using "CRC Throttle Body Cleaner". I've noticed better acceleration speed and idles perfectly without hesitation.

Here's a video on how to clean the throttle body assemblies:

Thank you for your reply, 01CRVEX. This is very helpful. What and where is the FITV located? I will try it over the weekend.
