  1. 9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    I have an 03 9-3 Linear and been trying to fix the dreaded p0300 code. The only other code to pop up for a little was a P0411, but for right now it's gone and I don't care for it. As for the misfires, I replaced my plugs with some NGK Iridium IX's all gapped at .037 inches and also 4 coil packs...

    Okay, so I know that these codes are relatively common, so pardon me if there is a go-to thread on the issues. I was driving along the highway when I had a backfire and lost power. I was able to limp off the highway and then home, but not before I stopped in and got a readout on my check engine...

    2004 9-3 Arc Convertible Turbo 2.0t with 180K miles with Brew City Boost Stage 1 ECU. Drastic temperature change here in the DC area last week (9/28/2017) from low of 60s down to low of 40s. Just out of the blue, the engine turns but it won't start. Coils and spark plugs are less than 2 months...
  8. 9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    Half way through the winter my 04 ARC when first starting her up in the morning would run rough for a good 10-20 seconds or until I gave it some gas and the idle would immediately clean itself up and stay that way for the remainder of the day. I could turn the car on and off multiple times...

    Hi, I have a 2006 9-3 2T wagon. I bought it for my son as a first car, and had nothing but trouble after about 4 months of owning it. My first problem was getting the codes P0204, P0203, P0202, P0201 & P0245, accompanied with the gas smell, white smoke and the other standard issues. I took it...

    My 04 SAAB 9-3 2.0t has a lean code, random misfire code, and a purge valve malfunction code. I did a fuel pressure test and got 10 psi while priming the pump and just under 40 psi while running. Car has intermittent misfires and bad hesitation at time. Any suggestions?

    Hi, Saab 9-5 2.0t 2004 I just changed the register chain and one of the exhaust valves (part of the spark plug broke a hole in it). Of course I had to drop the engine to the ground to get to the register. After putting the engine back together I'm reading a P0300 code and the engine does not...
  13. 9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    Ok so I know this p0300 code has been gone over hundreds of times. I have searched and have not found anything that matches my issue. I have a p0300 code that I have reset multiple times. It keeps coming back every time the outside temp drops below about 40 deg.F. when this happens is when I...

    I have a 2007 9-3 with 2.0T engine. A couple of months ago the car was hard to keep running after a cold engine start - the rpm would vary quite a bit after initial start, and drop so low the engine would stumble and kill. After 1 or 2 starts like this it would settle down and seem to run OK...

    We recently purchased a 2005 Saab 93 Linear for my stepdaughter. We've had a bit of a time with it so far. Replaced the front strut assemblies and had to weld a hole in the oil pan. Just when we thought we were in the clear......more problems. Here's the story. We were headed out the...

    I just bought a 2002 9-5 with 68K on it. This car was not running when I bought it. I replaced the CSP sensor, the spark plugs, several vacume hoses, DIC and bought a new battery. Now I can start the car and it drives for awhile but after about 15 mins it start to run rough and dies. Other times...

    I've reached the end of my tether! Had that shudder that some saabers have talked about with my 2004 9-3 aero. Had no CEL during that time. Changed the coil packs... didnt fix it. Changed plugs, both turbo vacuum control valves and all vacuum lines... didnt fix it. Drove it anyway, gingerly, for...

  19. NG900 & OG9-3 Workshop
    *Ok, so my saab 93 2001 2.0T SE has been having a rough cold start up in the mornings for the past month or so. The rough idling at start immediately stops when the gear is changed, or it auto corrects it self when waiting a few seconds. As of two days ago, the car threw out a check engine light...
