hey, guys. it's been a while. the old 86 iroc is almost back in action. problem i ran into is i have a few vaccum issuses after i did the rebuild. first off any ideas on where the hose connects to that you hook onto the intake plenum, and i see one thats in the rear passenger side not that it matters that goes to nothing. it runs! but idles screaming high. it has all new sensors and all that, now going through the vaccum lines. any comments/suggestions would be great. Almost forgot. it's the 305 TPI engine.

 

If there's not a vacuum hose on it, cap it off - vacuum leak will make your idle off.

This is the TBI section, not TPI - mods might need to move to get better response.

 

alright, sorry.dyslexia moment there.
