hey I wanted to see if I could figure out these vac lines, 1989 ea82 spfi. I removed the Charcoal canister and I cant figure out where the 2nd IAC line should go to. With them both off it throws a check engine light, but with the drivers side hooked up to a vac its dont. I just have the other one venting into the engine bay.

IAC or purge control solenoid?

well its on the front of my throttle body, two lines can hook up

Why did you remove the charcoal canister?

the nipples broke off!

Just looked at mine while under the hood and remembered this thread.

 

As you face the engine, right side hose feeds over to the charcoal canister, front most steel line on the bracket on top of the T-stat housing.

If you removed canister, that one should be capped.

Actual vacuum supply for the Purge solenoid comes from the intake manifold, and tees in with the line for the heater controls.

 

Hose on the left of throttle body feeds the EGR solenoid.

I had to reroute and tee in my egr because I was not getting any vacuum from the passengers side of the purge solenoid. I will try to get a pic
