Hi,
I have a Fiat Grande Punto 2006 1.4 that jerks around 30mph. If you are constantly changing gear or accelerating through the gears then its fine, however if you are keeping a constant speed around 30mph, after a while the car will usually start jerking (sometimes lightly, sometimes more violently). Changing gears after it starts jerking then makes it stop. It only appears to happen when travelling between around 30mph.
The spark plugs, ignition leads and air filter have been replaced but this has not helped cure the jerking round 30mph. Does anyone have an idea of what could be causing this based on this description?
Thanks in advance for any help / suggestions!
