I have a 52 plate Laguna 1.6ltr which has developed a 'stutter' between 2600 rpm and 3000 rpm.
The problem is only apparent under gentle acceleration and clears when car is driven hard.
It has done 87K miles and has full service history.
The fault is similar to a misfire but engine runs great out side of this rev range,Any ideas greatly appreciated!

I had the same problem - turned out to be a faulty ignition coil, apparantly a "known problem". My car was a 1.6 as well. "2002 - a good year for wine, a bad year for ignition coils..."
Covered under warranty at the time, but would have cost about 500 euros.
