missing vaccum hose
hello i have a problem with my '99 saab 9-3 i dont know much about cars but i will try to explain it as best i can in hopes that someone can tell me what it is, there is a vacuum hose that is supposed to be connected to the intake right where the intake pipe connects to the engine, it is i believe the onlyvacuume hose that comes out thepassenger side of the intake. well that hose is gone.
i started my car this morning and it was running really rough. i looked in the engine and could hear the hiss of air, wich lead me to the very small part of hose was hanging however i could not for the life of me find the rest of the hose. what i need to know is what does it go to. it is, like i said, on the passenger side of the intake, it points some what twords the rear of the car. if anyone could help me identify this, that would be great. thank you. |
RE: missing vaccum hose
can you take a picture? Did your car throw a check engine light? I suspect it's the MAP sensor hose, the sensor is attached to the strut tower bar on the passenger side...

RE: missing vaccum hose
yeah it did have a check engine light for a bit before it broke completely. i looked at it and it isnt the line to the MAP sensor. that one is still connected its further back on the throttle body than that. i dont have a camara but i am trying to find one, hopefully i can get a pic up by tonight. thanks for your help.

RE: missing vaccum hose
oooohhhh that....look next to the wheel well for the remains of it.
|
RE: missing vaccum hose
i looked everywhere and i cant find the rest of the hose, maybe it got ripped off somewhere down the line. what is it supposed to connect to? maybe i can find it that way.

RE: missing vaccum hose
well I'd lie if I said what the thing is..looks like part of the emissions system...connects to some sort of a valve located on the passanger side wheel well. I'll look into in the WIS, but I hadn't had much luck finnding specific things in there...
|
RE: missing vaccum hose
is it inside the wheel well, or in the engine compartment( like under the air box)?
|
RE: missing vaccum hose
in the compartment, like behind the shock tower...
|
RE: missing vaccum hose
It's supposed to connect to the EVAP valve and there should be another hose from the valve going to the charcoal canister.

RE: missing vaccum hose
thanks i found the hose and got it replaced but the car still wont start. it tries to fire but then shuts off imediatly. could that hose being broken have effected something else?
|
RE: missing vaccum hose
The non-start is probably unrelated...you will have to check if you have fuel pressure and spark.

RE: missing vaccum hose
hey roto thanks for all your help, i still havent gotten it running, but i havent really worked on it either. i was wondering if the no start problem may be with the ignition casset. i took my car to the shop a few months back and they said it was not working right and would need to be replaced, but i had a red one, and they replaced it with a black one, which they said was fine and it should work with no problems.
|
RE: missing vaccum hose
a black one does the job, but you really should have a red one. And your shop should be shot in the nuts...a black one is VERY different from a red one. The two cassettes sence knock differently.
|
RE: missing vaccum hose
do you think it could be causing my non-start problem?
|
RE: missing vaccum hose
If it went bad - yea. It's easier when you can find someone in your area who can swap cassettes with you to test it out...
