Hi I need a little help. My car has now started to what I think is misfiring quite badly. It doesn't do it when I first start the engine. After a few minutes it starts to hesitate badly and sounds like a Subaru Impreza. The cat also smells quite badly. Turn the engine off for a couple minutes, third it back on and still doing it. Drive it down the road then it clears and seems to be fine for the rest of the journey. I took it to Renault who diagnosed a faulty lambda probe. I've had that fitted and it's still doing it.
Anyone have any suggestions. I have read a lot about the coil packs going down but why would the cat smell?
Please help
