    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    Ok, I know that coils were discussed in hundreds of threads here. Each one of you knows the problem pretty well, but let me explain what is going on with me. I spent tens of hours on saabcentral looking for an answer but you know what, my Turbo X begs to differ. This thread is a combination of...

  7. Misfire? 2006 2.8T Aero 6 Speed

    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    Like the title says 2006 2.8T Aero 6 speed. In gear 3 and above. I get a "misfire" around 1500 rpm. It only happens on occasion and I've narrowed the symptoms down to very specific symptoms I believe. First there are no codes except for P0496-my evap canister purge valve. The lights been on...
  8. stumbling

    9-5 Workshop
    I experience stumbling/misfire with my '99 9-5 when then engine heats up. I particularly notice this on the highway with cruise control. I cleaned and gapped plugs last week as well as visually inspecting DIC with no change in performance. I replaced DIC about 5 years ago and the CPS was done...
  9. Feels like misfire with no codes?

    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    I have a 2003 9-3 linear and lately I've been getting what feels like a misfire only after the engine heats up all the way. Like I'll take a 20 minute highway drive and when I get back on regular roads I'll put some gas on it and it will feel like a misfire when switching gears. It is an...

    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    I have a 2000 Saab 9-3 SE. Recently i replaced the DI cassette and it was running smooth for a month or so. Then I had a couple of random misfires, no CEL, so i looked at the MAF and air filter. MAF was clean, but i needed to replace the air filter. All done now and on start up it happened...
  12. Strange Misfire

    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    I'm going to try to make a long story fairly short. Last Christmas, while on vacation, I stopped for gas at a major gas station (not sure I can list the name). Anyway, about 2 miles down the road, my CEL came on. I hoped it was just a loose gas cap. No such luck. I pulled into an AZ and had them...

    NG900 & OG9-3 Workshop
    I bought a 2001 93se about 2 months ago. Its my first saab and I was ok with the higher maintenance cost because I felt I could handle most of what I researched about basic repairs. I wanted to learn too, and im pretty technical minded. I mostly just wanted to have more fun going to and from...

    Hey everyone, I have a 2003 9-3 Arc, and just yesterday the engine started to crap out on me. While driving down the road, pressing the gas to accelerate caused the engine to shake and shudder fairly violently through all RPMs, and very little power was getting to the wheels. It's also very...
