Hi all Thank you Ian and John for your replies I have taken a sample of the fuel it looks good, changed fuel filter, checked cam shaft and fingers they also look o.k and no wear. Air mass on the road 3rd gear WOT is around 800 kgh, it does not give a desired air mass reading. There is also no fuel pressure reading in live data, but i removed a plug at the back of the fuel pump and checked fuel pressure there. At idle it was about 1.5 bar and at about 2500 RPM it was at 2.0-2.5 BAR. I take it that this is the pre supply pressure, can anybody tell me if that sounds right. Any advice would be most gratefull. Regards Jamie
