Smile Re: Renault Clio II - Engines - Poor idle when cold

My Wife's 1.4 52 plate 16V clio had a very similar problem, it would stall when cold, and was erratic until it warmed up.
In our case I traced the problem to a dirty throttle body , our one has the "fly by wire throttle" (no mechanical cable to the throttle only a electrical connector. This made sense as the electric actuator was slightly stuch so it did not control the throttle at all well.

I removed the throttle body and cleaned the residue near the butterfly plate and the problem was fixed - easy job so worth a try in your case.
