Hello,

My 2006 CR-V (4Cyl) has started to idle rough and make some minor knocking noise when the AC kicks on.

This is only at idle, it runs fine while driving and quick stops at a stop sign. The issue only happens while sitting at a red light or while parked.

I have done some searches and it sounds like (Forgive the novice) Idle air control valve ? Maybe?

The air compressor was replaced last summer and it has a new serpentine belt.

I would like to ask if I'm on the right track with the idle air control valve, and if so, I may need some help finding how to clean / replace it.


Thank you, I have been reading as much as I can, but am at the point I need to ask.
Dan
