Might be spark plugs or something to do with ECU. Mine used to be a bit jumpy at low speeds when starting from cold but changing the spark plugs sorted it. My mates old Clio had really bad problems with power dropping out though which was something to do with the engine management system.

I would try changing the spark plugs first though as I changed mine and made a huge difference.

thats just like this, only does it when its cold...

what make spark plugs would you recommend? original renaults? or aftermarkets? looks a big job to change them as there under the inlet, cheers
