all except "po441" is related to the spark plugs and DI Cassette - new plugs and replace the DI and those should stay away once cleared

as for the "po441 evap emission system incorrect purge flow" You may have a small vac leak near the Purge valve or a bad purge valve.

P1334 is caused by a misfire in cyl 3 or 4 or both, this could be plugs wires or if you have DI the cassette going out. OR like on my friends Saab in the US he had a bad ground from the DI (loose screws and corrosion under them).

Anything with an evap code in my experience is either bad hoses or bad canister.

Also if its throwing O2 sensor codes always fix whats upstream of the O2s BEFORE you replace the O2s, they are just telling you that the gasses arent what the computer expects to see, if your misfiring then you will get a running rich code, if you have intake leaks you will get a lean code etc.

Saabs IIRC use the DI cassette to figure out cam position, if the DI is going out that code will throw, I read this on another post a while back and the guy changed his plugs and all codes disappeared.

I would start with the cheapest and look at the plugs, tell us what they look like, burnt, black, oily, white/grey etc. Plugs are cheap and can fix alot, if not then you have new plugs and maybe a new DI.

Damn I type too slow ROFLOL but good to see there is a consensus brewing :)

There's a once per lifetime recall for the DiCs. Call Saab with your Vin and ask if it was ever serviced. Unfortunately it most likely was, and the DIs die more often than that.

Ensure the plugs are the OEM plugs ONLY (NGK series) if they are not the OEM exact plugs - you will destroy the DIC and cause other problems.
