    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    I own a 2010 93 1.8t auto which has Maptun stage 1 (220bhp) software on it. I have been trying to rectify the performance issue I have with the car for years now, but as yet no luck. The engine has a slightly rough idle and will sometimes feel like it is losing power or pulsing when...
  3. New Car Just Died

    NG900 & OG9-3 Workshop
    Just got a 2002 9-3 SE a couple days ago. I replaced the DIC and spark plugs with NGK Laser Platinums from O'Reilly's because of a misfire code. The engine was idling smooth before I replaced the plugs and DIC but there was a noticeable increase in performance afterwards. I took it back to my...
  4. 2002 Saab 9-3 Running and Idling Issues

    NG900 & OG9-3 Workshop
    Hi all, let me get started by saying I'm not posting to waste your time. If I had found an answer up until this point I would not be posting here. My 2002 Saab 9-3 SE has been driving me crazy, lately. It has been idling very rough and misfiring while running. It runs so rough, to the point it...
  5. Cut and Disconnected Hoses

    9-5 Workshop
    I recently bought a 1999 Saab 9-5 2.3 for next to nothing. Runs, drives, but stalls or falls into low RPMs while idling. I'm throwing two codes, but only one that's truly serious for the time being. It's P0300 a misfire code as it reads on the scanner. I checked my plugs and they're all good...

    Periodic misfire in cylinder 1 or 2 code P1312. Replaced plugs and cleared code, still comes up periodically. Bought NEW OEM ignition coil off rockauto. I swapped with one of the cylinders and engine sounded terrible, shaky, only 3 cylinders firing. Pulled out coil and put in an extra spark...

  9. Misfire started yesterday - only around 2500 RPM

    NG900 & OG9-3 Workshop
    1999 9-3 2.0t. 179000 miles. When cold, the car runs fine at any RPM. After it warms up, there's a misfire around 2400-2500 RPM. It 'seems' to be fine below and above that. When it happens, the tach needle bounces around a lot. This gives me the impression it's an ignition problem. I don't...

  13. Misfiring and jumpy idle

    9-5 Workshop
    Hi everyone, I'll try to keep this as short as I can, but I'm at a bit of a loss with my mother's '06 9-5 2.3t. Essentially, the problems started when the car developed a jumpy idle speed. When sitting at the lights (in drive), the idle would fluctuate between ~1250rpm and then dip very low...

    Hi guys, Long time, no post! Hoping for some help with what must be a pretty common problem, though I'm struggling to find suitable threads - probably because the keywords are a bit generic! Car is a 2008 Aero automatic with 80K miles. Regularly serviced, no modifications - bog standard...

    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...
