Following on from my other Zetec paranoia post, when I fire the engine up, it's lovely and revs really freely. However, it feels to me like when it's warmed up, sometimes it's only firing on 3. It feels and sounds a little lumpy at idle, with a slight vibration.

The engine is running on a base map at the moment, so don't know if it just needs setting up properly? As always, any suggestions or advice much appreciated!

Plugs and leads are a bit susseptable to that. Put some new plugs in and make sure everything is tip top.

Would also check for manifold leaks too.
