Intermittent bad idle after bhg repair

[zman6127]

Hey guys looking for some help. After my bhg repair I have had a bad idle. It comes and goes and is better when the a/c is on. My throttle body was crusty and would not clean well enough Ainu bought a used tb and also an isc. Replaced both and it was better for a few days and not its back. What do y'all think?

Also just found this vac hose not connected. The one end goes to the Afm bracket from the charcoal canister and the end I found loose idk what it goes to. Any idea?

if one end goes to the charcoal cannister then the other end should go to the throttle body (correct me if i'm wrong, i'm not familiar with the egr motors lol)

edit: do you have a boost gauge? If not grab a cheapie and see what your vacuum is at idle

The vacuum hose goes from the charcoal canister to the BVSV. It's the top most thing on the thermostat housing. There should be another line from there to the hard lines on the 3000 pipe.
