2003 ARC would be a V6 right?
Most likely it is the catalytic converter starting to get tired. Maybe that's why the car got sold.
You can always try with a new front O2 sensor since they need to be in working order but the V6 engines have a pretty weak catalytic converter to begin with and it takes a lot of beating from the oil that most V6 turbo units emits through the seals.
Most likely, the Saab indy can run a catalytic converter test using his Tech 2 scanner and most likely the car and converter will pass the test since Saab's way of testing is different from the Federal mandated OBD2 test that the cars computer run in order to set that code.
