IACV Connections

IACV Connections
Honda Smart People,
I have a 1998 Honda Accord with an F23A engine and a 5 speed transmission.
When my idle started to act up, I took a look at the IACV and saw that there was what appeared to be a vacuum hose dangling off of it. After my “Ah Ha!” moment, I realized that I wasn’t sure where this connection is supposed to be made.
Long story short the coolant hoses are connected to the IACV but the vacuum hose connected to the valve is not.
Any help would be appreciated!

Re: IACV Connections
I took another look at the lose hose connected to my IACV and it appears to be about 6 inches long. I felt around the area for anything that might be within reach of the hose but, I couldn't seem to find anything.
I have to be missing something.
Thanks!

Re: IACV Connections
After some extended asking around, it appears that the hose in question doesn't seem to server a purpose other than to provide a source of air to the IACV valve. It being not connected to anything hasn't effected the engine or idle performance one way or another.
This issue was originally encountered while we were looking for the source of a surging idle in my 1998 Honda Accord LX. This problem turned out to have been caused by a flap that was stuck in the IACV. We tested this by putting a finger over the port to the IACV in the front of the throttle body (I attempted to add the image below). Once the flap was cleaned up and lubricated, we reinstalled it and the idle ran smoothly with no surging. At first start it went to about 11,000 rpm and then went to 750 rpm after the engine came up to temp just as it should have.
I know this post has been read a number of times so, I hope this information might help someone else.
