I see no one else has posted an answer for you here yet so I will take a stab at it for you. The P1300 codes I am familiar with on the Saab's are P1334 and P1312 which almost always means the ignition cassette is failing. Most of the time the car will still run good, at least at first anyway getting worse over time. They are not cheap, ebay has the lowest prices and most availability that I know of. They are very easy to replace, just one electrical connector and four large torx screws right on top of the engine. If you have a black one replace it with black, red with red. To be absolutely sure you get the right one it's best to match part numbers. That being said most of the ones I have used have been interchangeable as long as they are the same color & # of cylinders.

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.

Your 'generic' codes are there for OBD-II

p1300 and p0300 Inspect the wiring, DI cassette, and the spark plugs are clean and making good contact. p1549 Check the charge air system and the air flow through the Turbo boost pressure control valve. These are relative the code you received.

P1300 is random misfiring. I suggest replacing your DI cassette with a known good unit or a replacement unit. Give more info on your vehicle. Any symptoms or running rough?
