where does this vaccum line go? or whats it for? right now its capped off, and i got a little bit of surging idle where it goes up and down and when i let off the gas it dips real low and almost dies. with it unplugged the car runs smoother but with a higher idle.

the one between the injectors

In front of the 3000 pipe theres three metal pipes that are welded together and run across the engine from tb to intake: the ISC, the vacuum for the BVSV and a third vacuum line for the BOV. I think thats the one for the BVSV.

With what unplugged? Do you have something normally connected there?


With it open, like the picture, it is a huge vacuum/boost leak. You will have very poor engine operation. Lean at idle, Rich at WOT.


check over all your vacuum hoses - http://www.cygnusx1.net/supra/install/vacuume_hose.html
and that one you have shown is #22205 on this page - http://www.cygnusx1.net/supra/library/EPC/MKIII_NATO/291420/2211_2.html
