In for ideas on this

I think mine does the same thing.....it's hard to explain really.....when I go to pull off my driveway first thing in the morning, the
front lights dim very slightly for a split second and the rev's do sort of drop/not change, and the engine feels like it will stall, but then sort of shoots up again (not at extreme as 2k rpm) This is using very light throttle and there's no issue after the initial 3-4 feet once I head off up the road.
I always figured it was the Clio's (crappy/frankly bull****) cold start issues, although I can't explain the slight dim/flicker of the lights.
