Metalliblob Posted November 21, 2011 Report Posted November 21, 2011 Hi,I had exactly the same problem as this with my 2.3 petrol.Turned out it was a coil pack breaking down and leting unburnt fuel into the system.I discovered I had a slight and I mean slight missfire every now and again. It was so small that I could only hear it when the car was in the confines of the garage.Well worth a check.Hope this helps. Quote
