rough running/juddering

[kingofhearts1961]

my tuscan spped six (53)has just devoped a problem, more noticable at slow speed around 30-40. the engine judders it has never done this before, full 12k service some 1000 miles ago including shim adjustments. it seems when at spped around 70 when holding it at that speed the problem feels like its there too. no problems at all with starting or accelaration. any thoughts. thanks

if it's only just happened since service, take it straight back and tell them mate. I'm sure you've parted with some hard earned cash to get the service done.

Is the engine juddering or is the car stuttering? I had this for ages on very light throttle. My throttle body butterflies were badly worn so on light throttle some were flicking shut then opening again even when keeping a constant speed. Hence the stuttering. Car park driving was a nightmare. Got to the point where i couldn't bare it anymore and got the roller bearing mod carried out by STR8SIX. So much better now, so smooth, and I've been told the car will stay in-tune a lot longer between services. Not cheap but well worth mod.
