Where does the Idle up valve air hose route to. I know that it comes off of the valve and attachesto a pipe but where does the hose on the other end go to? I cut it off while pulling the engine and forgot to mark it. Dammit Man!

Assuming I4, assuming IAC valve hoses. Which hose? There are; A/C idle-up, brake booster vac hose and actuator vac hose?

 

A/C idle up. A vacuum line comes out from the left end of the plenum it goes into the A/C idle up valve. Another hose comes out of the idle up valve and attaches to a pipe that runs under the intake manifold to another vacuum hose on the right side of the engine. I thought it went to the IAC valve put the size is wrong. So where does it go?

If you have a vacuum routing sticker on your hood, refer to that. The hose from the IAC valve routes to the Idle Up switch (as you know) the other hose from the idle up switch routes to the passenger end of the intake plenum, right on the end of it toward the firewall side. Don't confuse rubber heat shield on hose for hose size.

 

Got it thanks
