vaccum leak?

[XXX4life]

i have a vaccum line with vaccuum and i don't know where it goes? this might be why my gas milage sucks, so i swaped a DOHC into my SOHC car and my friend re routed all the vaccum lines and said they were all hooked up and accounted for then i get the car running and one of the lines has vaccum still? but i don't know where it goes? if i plug it the car dies? if i leave it open as i have been it's idling high, so the only thing i can think of is that it's gotta go into the intake manifold somewhere? anyone have aany ideas?? thanks

Maybe the fuel pressure regulator?

A vacuum source is required to decrease the fuel pressure under any vacuum...so without it hooked up, the injectors are spraying too much fuel unless you're at WOT (0 vacuum).

??? Just a guess...???

i'm not sure? my friend rerouted all the lines and i have no clue what he did?

[Richter]

Well, follow it and tell us where it goes..!

[XXX4life]

i tried following it last night and got my hand stuck behind the motor i will try again tonight

[mjjstang]

wtf, take pics or something, only thing behind motor was emissions shit from my recolections, sorry, been a while since I did any KA work.

[XXX4life]

yeah it goes to the emission egr shit somewhere, i'm just not exactly sure where

[90sr]

has to go to the fpr, thats wat i can think of, when u drive does it bog down at like 4000rpms and feel like its loosing power, if so has to be vacuum line going tot he fpr or i think theres one routed to the canister. good luck.

it doesn't appear to be bogging or loosing power?

[mjjstang]

it doesnt go to the butterfly valves or whatever the hell those things are, does it.
btw, it would be obvious if it goes to fpr or now, i mean the thing is just sitting out there inthe open right,

[90sr]

yah it would be pretty obvious but i dunno why dont u get ur cousin or whoever did it and have em look at what he did and see wat he says, cuz he should remember where he ran all the hoses. hope ths helps.

my friend that did the lines lives out of town, he's suppose to come down next weekend, also there is a line hooked up to the FPR already

[90sr]

well its a t clip thing on ur fpr, one to the regulator one to the intake manifold and one to canister ib elieve, i would just ask him cuz if he set up he should know what to look for, id have to look at it to tell. good luck.

well i know the canister in the front on the engine bay got removed

[90sr]

hmm thats get me thinkin now, maybe that vacuum line can get removed entirely, and just cap off the nipples on the fpr and whereever its coming from, (yah i said nipple) see what happenes.

chris

[mjjstang]

BUT, he said if he plugs it, the car dies, so he could not cap it, I think one of three things,
Have ur friend come back and redo it
get in there with a flashlight and find the source
go get a vacuum diagram and do it yourself, make sure everytyhings in place

Put it back!!!..Engine uses the Carbon cannister as a vacuum purge for the fuel system. It keeps your gasoline from evaporating into the environment. When the engine is running, the air is drawn thru the bottom of the cannister. Fuel vapor is reroutedto the intake manifold. Check your FSM for further explaination.

that is tru, i forgot he said he dies when he plugs it, hmm just get that friend over who did it and have him look at it good luck .

anyone have anymore input on the canister being removed? i'm gonna trace the line again today and find where it goes

[XXX4life]

i found out that the line goes to the solenoid on the back of the motor, the one on the passenger side, anyone know where it should be plugged into?
