You might want to go out and look around the engine for vacuum leaks, that would be the most likely cause.

Most common cause of rough running Renaults is a faulty ignition coil/s. Theses are found on most of the 16 valve engines and are the 'pencil' type coil. As your engine management light has illuminated there SHOULD be a stored fault in the ECU memory, most garages will have equipment to read the fault codes, however I have had Renaults that although the engine is clearly mis-firing the diagnostic tool has given the ECU a clear bill of health. Most motor factors will stock the coils so you do not need to pay extortionate main dealer prices.
