vac. line #3 broken?! help!

[CB7DX420]

So i finally got outside and was getting ready to do my FITV and IACV when i noticed the top port (not at the MAP box) that #3 connects to is busted off, clean off.

#3 connects to the top of the evaporative canister, my question is, is there anything i can do to fix this until i can find and purchase a used canister?

plug it off on the TB

So that would be cap off line #20 @ the T/B.
what about #3 tho? its just hanging off of the MAP box, do i want to cap that aswell?

would this have been the cause of my idle problems?

[RyanD]

yes and yes

[CB7DX420]

#20 doesnt seem to run from the canister, its a large red braided hose that connects to a port next to the base idle screw on the T/B, is this still what i need to cap off?

Will a slightly larger diameter bolt threaded into the #3 hose thoroughly cap it off?

i was just asking a friend of mine what the red hose is for the other day!

yes you can cap it off with a bolt. i would fold it over on its self and zip tie it for a temp fix. that should fix the idle issue because it is a vaccum leak. cap it off and fix it ASAP

ok awsome, thanks buddy! you cant even imagine how much i appreciate ur help!

[RyanD]

no prob man thats what we are her for. let us know how it turns out

[CB7DX420]

will do man. gonna go fix her after some bob marley lol

[CB7DX420]

Wtf?

Ok guys so i capped off where the red line attatches to the T/B and then capped line #3 and tried to start the car, REFUSED TO START!

I dont know why or how so I just un did the caps and put it back the way it was, i pulled the back up fuse and now it starts and idles perfect even under load of AC & lights.

So why would restarting the ECU make it run right again, and why in the hell did my car not start when it was capped?!

[CB7DX420]

Drove her around the block, still problematic!

every time i roll down the hill in neutral with the clutch in it jumps to 2000rpm and then it'll hang at 1600rpm at stop signs for about a second now and then drop to 1000rpm

I dont get it and its really getting to me that i cant fix it...

When I un capped the previous port (the large port that the red hose off the charcoal canister connects to) and removed the plug in line #3 and re started the car, it was pissy to start. I reset the ecu with the back up fuse and it started, idled @ 2000, dropped to 1500, then 1000. all in a very nice fashion.
HOWEVER when i was under the hood the #3 line was pushing air out of it, I thought it should be pulling in?

read a little more, and i need to know:

Do I cap the port that vac. line #20 goes onto @ the T/B? instead of the port the red line coming off the charcoal canister attatches to?
the #20 line attatches to the "purge cut-off solenoid valve" inside the black box on the firewall that contains the MAP sensor.

according to the diagram i found, the #20 line runs from the "manifold port" to the "purge cut-off solenoid valve" out of said valve labelled as "#3" leading down to the charcoal canister's "purge control diaphragm", this line (#3) is the line that is not connected due to the canisters "purge control diaphragm" upper nipple being snapped off.

When capping off said port @ the T/B for line #20, do I also need to cap line #3 coming out of the "purge cut-off solenoid valve"?


thanks for any answers in advance, im praying you guys can help me figure this out!

Why can't you go get another box from the junk yard?

[CB7DX420]

I didnt have any money but I finally got the cash and went to the junk yard, the first one i went to wanted $80 and i blew up in his face over it and left,
I called a junkyard here in Pendleton, $20 i'm gonna be giving them all my buisness from now on

So here in a couple hours ill pick up the canister and get down to replacing it on the car, I'll let you guys know if that resolves the idle issue
