Thanks for the input. If it was only the idle issue I would easily believe idle stabilizer. The issue I couldn't fit with this is the occasional stumble, stutter on accel between 1000 and 2000 rpm.

Can't recall when I last seen a S2 on the road or a 944 of any sort around here.PCA really needs a way to connect these questions for ongoing issues. Sort of a forum type thing. Might make it easer to follow.

He had similar difficulties with another German make that was still very much current production for service. Their parts guys used to be great though. Now parts has gone downhill too. Not being able to get the right sensor using the VIN and Porsche computer system is, well ...
