Carbon building up in the throttle body and idle valve?

Getting a weird idling issue when I come to a stop and my AC is on and even worse when the AC is on and on the brake pedal. The idle drops really low and the car feels like it's going to stall.

Honda tech said it's carbon build up on the throttle body and idle valve? What did you guys use to clean it up besides taking everything apart?

For the IAC you have to take it off/apart to clean it.

The IACV is just two bolts, Take off the oring/metal screen and clean the valve with Carb cleaner. If that doesn't fix it you might need a new IACV.
