Missfire

[rupe30]

Car's developed a missfire recently.

When starting the engine cold I can't even pull away as I am unable to build up enough revs. When it's ticking over the revs are very low and it sounds like its about to stall.

Once warmed up the car runs ok, so I thought it was just a bad bit of fuel going through, but then it came back pretty quickly. Pops and bangs very loudly when it missfires.

Any idea what this issue is? No engine light on.

First thing i would do is change your spark plugs, few people have had problems with them causing a missfire. Renault say change them at 36k but mine needed done after only 18k.
