12111 is an o2 sensor adaptation fault - throttle open. http://www.saabnet.com/tsn/faq/lhoverview.html Does the light illuminate at idle or while running? Does it run better at idle or under power? First, make sure that the idle switch is adjusted properly. Then, make sure that there is no vacuum leak. Look at hoses, fittings, etc. when it runs rough, can you tell if it is rich or lean? This would help. How old is the O2 sensor? This would not cause a bucking condition, though.
