Hello I've just bought a PUMA 1.7 1998 and it seems to have a juddering problem. The juddering seems to be quite hard. It happens usually when I'm lifting of the accelerator pedal. I've heard the possible cause of the problem could be the hego sensor. I've disconnected the the hego sensor connector and it still juddered. I've disconnected the throttle position sensor connector and it stopped. Any thoughts? Thanks.
