So that is a CRV motor right? What problem are you having other than that? Those ports are for the idle air control circuit. Air has to get past the throttle plate at idle via those holes. I believe only one should have vacuum at hot idle.

Yes

Does your engine have the fast idle valve?
The one that is sucking is for the IAC.which
bypasses air when the throttle plate is closed.
if your car has the FICV this other port would
be for this.
