Had a full service becuase of a rough running engine - but still stuttering...

Had the Clio fully serviced a couple of weeks ago, everything was changed!

The start up has definetly improved but when im in low revs the engine stutters quite badly, when I get roughly over 4000 - 4500 rpm its fine.

What could this be?

oxygen sensor. measures light load fueling and allows the ECU to make fine adjustments with the feedback. When they break, the ECU gets incorrect info

found one on euro parts which i can pick up tomorrow, are they easy to fit? or is it a garage job?

just get a garage to do it, they have a habit of being speed tight underneath

Had it at the garage last week turns out it was a dodgy HT lead, one of them had become wet and was arcing out causing a mis-fire. Me and a freind put in a new set of leads over the weekend - Problem fixed!!
