Car running rough - sorted

[Downlands]

Just wanted to say that thanks to the wealth of info on Blatchat, I managed to sort today a rough running issue I've been having with my 2007 R400 Duratec recently.

For the last 4 weeks, once the car warmed up, it would start sounding rough and hesitant up to around 4k rpm and this has been getting progressively worse. I found a few past threads on Blatchat where people had described similar issues.

Following the advice given by cleaning the crankshaft sensor in situ and then removing and cleaning the camshaft sensor, the issue appears to be sorted so that's a huge relief..... I had visions of an expensive trip to a specialist.
