  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...

It’s been throwing me p0300 codes...i’ve changed the spark plugs to ngks(old ones looked good) and tried unplugging each coil pack one by one(while car was running) and each time the rpms dropped. Not really sure what else is next. Car feels like it runs fine, so i’m not...

    We've taken our 2001 saab 9-5 SE 3.0T (lol) V6 on a seattle-to-LA road trip every year for a few years (2) perfectly fine. The third year, the car made it about 6-8 hours into oregon, started misfiring, and died shortly after. To make the story short, we rented a car to get to LA and I picked up...

    I was driving my 2007 9-3 2.0t convertible on the interstate the other day, suddenly the car started running very rough and the check engine light started flashing. I pulled over, (didn't shut the engine) opened the hood for a quick visual. Minute later the flashing and check engine light...

    Hi guys I was wondering if any of you had any ideas about this problem I have. Basically I recently got me an OG 9-3 which came with a black DI cassette. I know this is a tronic 5 engine (oil cap in centre) and I wanted to use the correct cassette so I bought a red one from ebay which the seller...

    Cylinder(s) misfires upon starting the car and stays that way under all rpm in neutral or under load. Leave the car out for a day or two and the problem is gone. I start the car again and it runs perfectly. I turn the car off for a few hours and go to start it... the cycle repeats. What's wrong...

    I have an 06 9-3. I have had a misfire I can't figure out. When I reset car by touching POS and NEG together every thing starts off great. After a a few miles the check engine light comes on and it misfires like crazy at increasing rpm. Light is crankshaft position sensor. Actually it says...

    Hi all, I'm nearly stuck on my search for the cause of a mystery misfire in cylinder 1 of my 2007 Saab 9-3 Aero 2.8L Manual... My BlueDriver code reader is spitting out P0201 and P0301, and after replacing the cylinder 1 coil and plug, all the injectors, and performing countless tests, I have...

  14. 9-5 Workshop
    Hello everyone, longtime lurker and Saab owner here. I've recently been given the chance to purchase an 07 9-5 Aero, but the owner describes the car as "the car jerks when you go to accelerate and the engine light starts blinking". My first instinct would be either the throttle body or the DIC...
  15. 9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    I've been getting a weird surge or misfire lately right after stopping the car after creeping along, like navigating a parking garage slowly. It doesn't happen all the time so it's hard to tell exactly what it's behavior is. I don't think I have bad valves, the car starts up immediately when...

    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...

    Had my 2006 9-3 estate with the 2.8t V6 (auto) for about two weeks now and had no major issues so far (apart from a bit of coolant escaping but was topped back up) On Sunday afternoon I drove less than a mile when the car started to judder quite violently at low rpm then just died, after...
  20. 9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    Hi everybody, I have had a misfire issue on my car for quite some time. It hasn't gotten better or worse and the car keeps chuggin along. The misfiring occurs when I press the throttle 50% or more. The car then shudders pretty badly. I was getting acceptable MPG, SID usually estimated around 21...
