I recently bought a V reg (1999) Astra, its great, drives well. There is however a small problem, every now and again when cruising at a set speed (usually around 30-40) the car starts to judder and bounce, if you put the acceleration down abit further the juddering stops and everything is back to normal again.
Its quite hard to describe but it usually happens at a steady speed, the juddering starts off only slightly and if u dont move the pedle will increase until its quite violent, its getting quite annoying. I have taken it for a diagnostic check which says one of the sensors on my front side ABS has gone, could this cause the problem?
