Hello, Thank you all for your responses. Over the weekend I managed to read out the trouble code on hand of a Bentley Service Manual, which, by the way, is an excellent publication to have if you own a Saab. I should note that the car has a 16 valve engine, with an LH 2.4 engine management system. The stored trouble code is 12111 (oxygen sensor self compensating circuit problem, incorrect air-fuel ratio while driving). While I was able to check for air/vacuum/fuel leaks (none) and operation of the ELCD system (the valve is clicking), I neither have the proper tools nor detailed knowledge to check oxygen sensor, fuel delivery system and whatever else. So, today I took the car to the shop. I will keep you posted of the outcome. Thanks again.
