This can make a big difference. This was one of my thoughts. Mixture doesn't necessarily mean that the fuel system is wrong or over-fuelling (although I don't know what the codes mean); it could be that there's not enough air getting in. My last 900 had a lumpy feel and after tinkering with the air/fuel mixture screw and the throttle stop for ages managed to solve all the problems with a simple air filter replacement. Good luck, Paul 1989 900 Turbo S http://saab.go.dyndns.org/
