I attempted to install my y8 mani on y7. PROBLEMS!

Once I took the old y7 mani off. I got the y8 all set to be installed

I put the vaccums on and coolant lines in place. And connected all the sensors.







But I have nothing for the tb lines. They disappeared. Ive looked on my buddies

car and I dont have these lines. My car isnt running 2 rich. But idles really bad

it does between 1500-3000. Dont know what to do. I need HELP anyone know

thats up with it. I'm trying to get this dude to help me out but I can't get in touch

with him.

Are you talking about the lines that run to the IACV? Your problem sounds more like a vaccum leak to me. Does the idle fluctuate?

 

what year intake mani did it come off of? reason is because if it is a 99-00 intake mani, you might need to plug up those air injection holes...check the link below.

Yea his idle goes up and down consistantly. I have a 1997 y8 in my car and we used it as sort of a schmatic but there were 2 fittings on his mani/tb that I couldn't see on mine. Not sure why but perhaps it is like that guy said about the 99-00 y8. Bump for drubie.

 

Did this IM come off a AUTOMATIC or MANUAL?

If it's a 99-00 there was a recent post here that show the holes you got to plug.

Thats the link to the Post.

 

guys.. please read up.. it's not a 99.... i would say double check all your fittings.. make sure the map/tps sensor is connected right.. nothing loose.. also are you using a y7 or y8 intake gasket ?

 

y8 gasket.

 

i used a y8 gasket on the manifold. But i still dunno where the vaccum lines go on the TB.

 

Is that a y7 TB? Is your car a auto or 5 speed?

 

i used the y8 tb and its a 5spd.

 

and you said there are no coolant lines?

 

how many wires go into the plug on the y7 iacv vs the y8 iacv?

i have no lines connected to my tb. Just the 3 sensors.

y7 iacv vs the y8
on the Y7 (3 wire) and the Y8 (2 wire)

 

use the y7 TB on the Y8 Mani... cover the IACV with a gasket. All you need to do is unscrew it and place a gasket over the holes. Once you do that and use the Y7 tb there will be no leak. If you just use the Y8 mani and dotn plug up the IACV on the Y8 there will be a problem. Use the Y7 tb and y8 mani(oplugging the IACV) then you will be set

 

i'll still have no vaccums to the TB tho?

 

there shouldnt be vaccum lines. Its should be coolant lines

 

thats wut i meant. Theres no coolent lines going into my tb.

 

If you want to take care of the IACV problem do what I listed. You maybe having a problem because of that


There has to be coolant lines. Can you take some pics of the TB then? Maybe I can help you from there?

 

true, I might have those lines connected somewhere on the Mani instead of the TB.

 

Let me know what I can do for you. I'm in the NEW YORK area.

 

luckily im in the midst of doing a y8 swap so i can tell you where all those lines go. Ok there should be a line coming from the waterpipe right underneath the mani to the leftmost hole in the IACV. The other hole on the IACV goes to your TB, the side facing the firewall. The other side facing the grill goes to the small port on the coolant bypass line. That should do it, if you need anything else PM, becuase i've done this

 

I replaced the TB with the one from the y7. The idle jumps back and fourth

between 1500-2500. So there has to be a vac leak. I'm just doing something

wrong. I snapped a couple pics.

Dont know if these will help but here:















I couldn't find those coolant lines for the TB. I really need some help. If anyone

wants to give me a hand. Im in the NJ, Princeton area. Im still gunna try and

figure this out but as of right now i dunno what else to do.

Thanks Drew
