i think that it comes from the lower intake manifold but i cant find out where it goes. my car dies at idle and i think that it is because of this. we put a bolt in it but it doesnt help

 

can I get a not so close look of the area. May help, and what year is the car also turbo or non-turbo.

 

its a 88turbo II.


and heere is another pic.

 

sorry I am out... I know nothing about tII's or the s4 system... maybe after I get one and tear it down and rebuild it tho

once again sorry I am no help.

 

can anyone else help?

 

i dont see the vacuum?...what exactly am i looking at?

 

i'm not fammiliar with T2 eather but that does not look like a vaccume line. it look fuel or coolant sized, maybe coolant.

 

could it have anything to do with maybe the cold start system? mine doesnt get that 3000 rpm launch when i first turn it on. should i just put a plug where it comes from or what?

 

could be a vacuum leak, pics don't really help, or maybe somehow your AFM, air flow meter, can unplugged

 

are you talking about the hose with the bolt in it ???

 

where's the bolt? I see connected vac lines, heeter hose, fuel hose, and cruise control linkage

 

are you talking about the vac hose going straight down from the fpr? if thats the case then you can plug it into any vac source as long as it's getting a proper vac signal. I have removed emissions and mine goes directly into the nipple pointing toward the firewall in the middle of the lower intake manifold.

 

in the first pic, are you talking about the one with the bolt in it? it looks like the coolant hose that connects to the outside of the BAC valve. it supplies water to the thermowax and might possibly affect you ridle.

dunno, hope that helps

 

yeah its the one with the bolt in it. but i believe that my bac already has all of the hoses it needs on to it. i think that this hose comes from the lower intake manifold. does it matter at all that this is a j-spec motor with us spec upper intake manifold and throttle body? somebody please help! i cant even find a FSM online anymore

 

ohh...i knwo what that is...its attached to the bac right?..it was suppose to be connect to the acv...but since u have emission removed..the acv also connects to the stock TMIC..so if u have that u'll need to plug it up as well....if u leave that open u'll have a vac leak..so plug it up..its fine...i shortened that tube so the bolt is right next to the bac

 

if im wrong then please take a pic thats not so zoomed in

 

yeah its not attached to the bac, and i still have my acv installed. i will try to post another not so zoomed in picture.

 

Do you have the stock TMIC? Is there 2 places(nipples) to hook up vac lines in the right rear of it? Or 1? If one, someone has put the 89-91 TMIC(only has one nipple) on it and left this open? Your IC should have 2 lines going to the right rear. One is for the BAC and one for the Idle to the Throttlebody. If you only have one, and it's going to the BAC, block off the BAC and put this loose hose on the nipple on the IC were the BAC was going. This hose is probably smaller than the BAC hose so a reducer fitting might be in order. stephen.

 

nah that aint it. i checked and both the hoses to the intercooler are there. this one line i cant just figure out. does anyone know existing websites to get the FSM off of? i tried aaroncake but i dont think it works.
