2004 saab 9-3 aero Trouble code p1312( 02s,switch point-rich sensor 1) I put new oem plugs in, the code still comes up and the car does not want to accelerate, it jerks when I depress the pedal more than halfway.

Yes it does. There are many causes from poor fuel grade to timing issues. I would take it to a SAAB garage for service.

it should be behind the front front bumper liner/lower vent area. a new part is best purchased from a saab dealer. hope this helps

Here is what I could find on it:

P1300 Random Misfire Detected. Catalyst Damaging.

Chances are that the Saab Ignition cassette is failing. You can find them on ebay, I recommend a new one since it is a common failure. Best to put new plugs in it while you are at it.


Easy to change, you just need a T-30 Torx (4 small bolts)
and one electrical connector on top of the engine. Oh and a good spark plug wrench.

Change heater output temperature sensor.That is a SAAB dealer job.

1. How did you obtain the message about something is in the trunk? I take it the top will not even begin to move when you try to operate it.

I have a 2004 Saab 9-3 Arc convertible that had the same problem. The spring on the hinge assembly for the package shelf latch assembly was broken. The part itself is over $300. If you have someone remove the spring, your top will work again. You'll just have to put up with the top shelf hanging down in your trunk about 1 foot, but you can still manually move it to place things inside like your luggage or golf clubs.

my saab is making a rowing sound in front drive bearing area

Sounds like car is in limp home mode which needs reseting ,which may indicate you need a new Di Rail, or throttle body. Is engine management light on all the time if so Needs reseting. Hope this helps.

Had same problem, in the boot right hand side, behind the removable panel there is :
1 - a hydraulic reservoir which must be at correct level.
2 - a black box (stc) this controls the roof system,
switch ignition off then pull the 2 connectors off for 30sec then reconnect.
This worked and hope this resolves your problem
