Slight Missfire

[Matt_Clio172]

I had my coilpack and spark plugs done the other month. Every now and again there is a slight missfire at around 2k. Any ideas?

Mate mine does it most days when i first start it up for about 2 mins. My mates 182 does it aswell he took his to renault, they cleaned all the inlet manifold out and changed the plugs and coilpacks it was fine for a couple of weeks but then went back to how it was before. But it was always ok once the engine had warmed up.

But you can hear the missfire on idle about every 20seconds?

No mine doesn't do that

Its normal, mine runs very similar. Sounds like a missfire but isn't, they just idle roughly.
