Where does this vacuum hose go?

Sorry to start a new thread over this, but I've been searching the forum and cant quite find the right answer.
So i circled the hose that im talking about in the picture, i just noticed that its not connected to anything today... So where does it go? and what size hose do i need?

Thanks!

No ^!

It is the vacuum hose that goes right there to the secondary air valve. You should see a nipple right next to your vacuum hose. It is a short piece about 3 inches that connects to a hard plastic hose about 1/8inch . It gets brittle and can break easily.

Both are right...it's the sap vac line, going to brittle pipe then attaching to a port behind the intake. You need to remove the cabin air filter housing to 'just' get to the other end. But, if you notice the hose cracked there, odds are you just need to fix it there, at the sap valve with the short section.

Some just replace the entire line with one vac hose...that plastic pipe is stupid expensive for what it is!

just do that end for now. Mine cracked a bit on the valve, I just dabbed rtv on it coz I didn't have any hose...it held for years.

Pick up a short section of vac hose for that...snip off a bit so they can match it. be careful with the plastic hose...it's brittle.

Get at least 3' of hose so you have enough if things go bad! lol

No, that will cause issues if it's cracked aft of the valve...it'd 'read' as an airleak.

Clear your codes and see if they come back.

Alright I'll do that. Hopefully that was the problem. I hear the CCV isnt a hard DIY but it looks really awkward.

No it has nothing to do with misfires. It only deals with cold starts and turning on the secondary air pump.

Capt, you might be right about that, but I thought the back end of the vac pipe goes into the manifold. There might be a valve at that end, though, which closes off the vac line from there. I thought it was open up to the valve, but I guess since there's no electrical connection on the valve, it is controlled from the back end of the line.

He's probably right, OP.
