I have all the coolant/vacuum lines hooked up but can't find where 2 of them go. there are 2 plugs on the si manifold for hoses. 1 is on the bottom of the throttle body under the intake inlet. the other one is by the #4 injector under the fuel rail by the block.

any clue where these go?

 

does this help at all?

 

the one by the fuel injector is for the pcv valve..

and i dont recall a vacuum on the bottom of the throttle body,only one on the top for the charcoal canister.

 

it might not be a vacuum under the throttle body, but there is a piece under there for another hose.

 

which hose is the pcv valve?

 

its the middle hose on the intake mani. where theres 3 hoses.

 

no no, not that one ... the other one. The hose by the #4 injector (dizzy side)

lmk

 

 

its on the intake manifold by the block by injector #4..... that picture doesnt show me anything.

 

where are the MPFI people at on HT?

 

graduated to the bigger and better motors. but theres so much info here it wouldn't been hard to fine. just patience.

 

Are you talking about the coolant line that runs from the intake mani to the IAVC??

it isnt picture in that picture.


that is the 1 by the block that I was talking about. the other one is below the throttle body inlet. it looks like it might be D on that 1 pic but I can't tell.

 

thats a coolant line.. you need the C shaped coolant line from the mpfi engine. or buy a new one. lol odnt hook that up to vacuum or your going to blow tons of smoke out your engine. D on that picture should hook up to the first vacuum inlet on the throttle body .. you can see that one in the picture i posted.

 

ok, i replaced the coolant hose.

but I still need the one for under the throttle body inlet. i'll try to take a picture of it later. It wasnt pictured in any of the pics in this thread.

 

Ahhhh.......A pictures worth a thousand posts!! The nipple in question now is for coolant. There is a choke under the TB that runs from front to back. You pull coolant from the intake mani into it and run coolant out of it into the IACV or Idle air control valve. You will see this on the back of the mani. Run the hose to the left side of the IACV. Hope this helps!!

 

ill see if this is the answer to all questions when I get home later on today.

 

good luck im doing mine soon

good luck with yours ... they arent hard (wiring is easy), I just wish there was more info on the vacuum lines and coolant hoses.

 

imo the coolant lines were pretty straight forward.. vacuum was a little hard. but was easy to figure out.
