Presumably you have a spam filter. I have a 1993 9000 CSE LPT. About a year ago I had the catalyst replaced at about 112000 km. There were also spurious hesitation symptoms that was difficult to diagnose, but the CAT was rattling when knocked by hand while car on a car lift, so I had it changed. It certainly helped. If it is not the CAT, then check the sensors. One sensor to look for is the air mass meter near the inlet hose. The sensors are all connected by a catch plug. Check that all such plugs you can find under the bonnet are secure. Regards, Johannes
