    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop

  2. Rumbling noise when letting off acceleration

    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    Whenever I let off the acceleration at any gear or any speed I hear a rumble for like 5 seconds and it stops, sometimes comes in when I’m braking too. The rumble is coming from the front end, sounds like the right side but I can’t tell if it’s center or right. Also whenever letting off gas while...
  3. How to decrease acceleration hesitation from a stop?

    NG900 & OG9-3 Workshop
    Hey guys and gals, What is the deal with my auto 9-3? Maybe someone can tell me if this is related to engine management or if it is even fixable at all. Seems as though I can fly around town just fine getting in the boost with my hair in the wind. But when it comes to that initial acceleration...

    9-5 Workshop
    Hello all, I recently became the excited new owner of a sleek 2008 Saab 9-5 in Titan Grey, an amazing upgrade from the 2004 9-5 Linear I was sporting before.

  6. Cold Natured Saab

    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    So I replaced my ECU today on my '06 9-3 2.0T (Thank you Brew City Boost! Stage 1) and all of the problems that I'd had have disappeared. My A/C works now, and the car has dramatically reduced the number of personalities that it has. It has reduced to only 2 now... hot and cold. When the car is...
  7. Slow off the line

    9-5 Workshop
    Hi all, Bit of an on going problem with Mum's 9-5 regarding slow acceleration. Basically, it is an intermittent issue where the car will be very sluggish off the line, and only gets moving after roughly 3000 rpm. Once moving along, the slow acceleration is not as noticable, however it is still...

    Hi Sorry for the non-technical description! I have a 2009 1.9TiD. I've been having a very intermittent (approx. once a month) spate of... lumpiness (for want of a better description). For a few hundred yards the engine seems lumpy and reluctant to pull, then it sorts itself out and is...
  10. Stuttering under acceleration

    So I have just recently hit a wall of problems with my saab, water pump went, o2 sensor went, and now the car stutters under acceleration. The car has been running on a bad o2 sensor for quite a while if this has anything to do with carbon buildup. I have also been told it might be an ignition...
  11. Strange smell when accelerating?

    9-5 Workshop
    Just bought my 2000 9-5 wagon about 3 weeks ago. I get a strange smell when accelerating, but only when I can hear the turbo spool up. It kinda smells like oil but at the same time not, maybe even dust? Could it be the turbo itself? The heater is not on, nor is defrost for windows. Any help...

    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    This issue started a few months ago and I can repeat the problem, but it hasn't really affected normal day-to-day driving, so I haven't made it a priority. Ok, so did some reading around the forums for engine stutter and have reached 2 common causes: an issue with the fuel system or ignition...
