Apparently happened a while ago, and had mechanic look, but he said everything was ok.

Anyway, SWMBO text this morning saying it was doing it again, and was very loud. Same on the way home.

I'm bringing it to work tomorrow and get it on our demo diagnostics machine. I'm hoping (from a Google search) it's just the Idle Control Valve.

Has anyone else had experience? It's a 1.3 Ford Ka 54 plate. Really hoping it's nothing major as we've just spent a fair bit sorting some common bodywork rust on it.
