I have a 2002 1.4 Jazz CVT with 40,00 miles completed. The car developed a problem with juddering. Usually at low speed once the engine had warmed up. On the open road everything was fine. With gentle throttle in town, it was juddering badly. Taken to local garage who suspected sticking in the throttle housing. This was duly stripped and cleaned and we were advised to drive the car for the car to relearn parameters. It improved for a couple of weeks, but the problem has now returned. It's also 'lumpy' at higher speeds now. The car was serviced less than 2,000 miles ago.
Rather than repeat the process, I thought I would seek advice from the forum.
Many thanks
Peter
