62 plate Ford Focus 1.6 zetec (petrol) judder!!

Hi folks,

Im after some help. Bought a 62 plate Fors Focus 1.6 zetec from Busseys couple weeks ago. I sent it back in today as there was juddering when taking foot off the gas from 70mph. They re-aligned wheels and updated PCM? Anyway so that particular problem has gone but now when Im in 4th gear and accelerating, at just around 3300-3500 revs it judders. I can’t feel it in the steering wheel and its not like a misfire, but I can feel it judder in the pedals and my legs and back. It doesn't do it when Im off the acccerator but just when I accelerate. 2nd and 3rd are ok I cant really feel anything in those but 4th at just before 3.5k revs is when I feel the juddering.
Going for a drive with the master technician Monday, any suggestions? The car has only done 41k miles.

Sounds like it needs a set of spark plugs. The earlier version of this engine was reknown for leaking core plugs which resulted in water leaking into the spark plug holes which caused a misfire.

That'll be a misfire then.
