I just bought a 2002 9-3 SE that has a funny issue. Only on the first start of the day the RPM comes up to 1300 - 1500 and as it starts to come down to idle the engine will shudder and the RPM will drop to around 300-500 RPM and than catch itself and run normal after that. You can shut it off and start right away again and it won't happen again. Only after sitting overnight. It has also stalled once while doing this. Anyone had any similar experience with this??
