  1. 2.8 Vacuum Pressure Switch (Sucking Air In at Base)

    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    The vacuum pump on my 07 2.8 has been running non stop. I disconnected the pump for the last few days. Testing the vacuum lines it turns out the pressure switch is sucking in air at the base. The base shaft has a slit built in by design so I am not sure if its suppose to do this. The vacuum pump...
  2. Help me find my air leak!

    9-5 Workshop
    Hey Guys - I started an earlier thread that was closed that discussed the performance issues I have been plagued with that affects acceleration on WOT, and I thought I had resolved my issues, but it seems they are back and I am not sure where to start. I do have some useful information...
  3. MAP/Vacuum problem

    NG900 & OG9-3 Workshop
    Hey guys I am new to the forum so I'm not sure if I am posting in the right spot. So I have a problem with my 2001 Saab 9-3 2.0T. Every time I drive around and hit the brakes, my engine just completely shuts off. Whether or not I'm pressing the clutch. When I ran codes I had P0106 and P0300...

  5. Brake Booster estimate...

    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    So I've gone through the forum here, found that brake booster vacuum loss is common. I go to my regular mechanic (I just bought this car, he used to work on my Grand Cherokee) and he said he doesn't touch Saabs. (Only works on the easy stuff I guess). He recommends another shop. They want to...
  6. Where does this hose go?

    NG900 & OG9-3 Workshop
    I thought I had my vacuum leak fixed, but my catalytic converter has gone lame (P0422), so I went around looking for more leaks. Don't want to blow a bunch of money on a new one until the cause has been discovered, of course. And lo, a hose was found disconnected. The hose is #7 in this...

  8. Strange Idling only on startup after replacing water pump

    9-5 Workshop
    Hi everyone, first post. Been using this site for years now and have saved literally 1000's of dollars. Thanks so much. 2001 Saab 9-5 2.3T with 225k miles, pretty certain the engine was replaced at 120k (that's what the previous owner told me). The car was given to me for free, so was pretty...
  9. Vacuum at idle

    C900 Workshop
    Greetings, Lately I've been looking for vacuum leaks in my '87 900 turbo. The Bentley Manual says that if I have between 12 and 24 "Hg at idle I'm okay. I can't take this spec seriously given the range of values. I measured 15 "Hg when I plugged a vac gauge into the small line that shares the...
  10. 9-5 Brake booster replacement - the easier way?

    9-5 Workshop
    Hi guys, The brake booster (a.ka. servo) on the 9-5 MY 2000-2001 is prone to leak at some point. As it is not serviceable in or out of the car, if it leaks it has to be replaced. With some borrowed knowledge, I was able to change mine in a more straightforward manner than I saw written up on...
  11. Vacuum Leak Maybe?

    9000 Workshop
    When my 9000 turbo heats up, it will die every time I push in the clutch and brake. It doesn't do it as much when the car is cold. I have replaced most of the vacuum hoses. Any Suggestions?
  12. Vacuum troubles

    C900 Workshop
    Hello, Can any one tell me what part this is and how to fix it? I think it is a PCV Valve but have not been able to find any that support two inputs from hoses. The car is a 1991 Saab 900 turbo 16 Valve 2.1 Convertible. The hose does not fit into the place where it should go.
  13. mystery hiss

    9-5 Workshop
    I have a vacuum leak on my 95 and I just cant seem to find it. I replaced all the hoses coming out of the vacuum pump. The leak sounds like it is coming from the area of the fourth injector, the one in front of the driver. I'm ready to pull my hair out. I really don't want to take it to a...
  14. brake booster hose concern

    NG900 & OG9-3 Workshop
    I went to replace my my brake booster hose today on my 96 900 SE turbo (automatic). The part is almost right but lacks a t-junction in the longer line heading away from the booster (with the straight check valve). On the original part a thin vacuum line ran from there to a sensor (pressure...
