Thanks Rob,

I am not a qualified mechanic however i did think that it seemed odd that the voltage stayed at 0 for a few of the screenshots.
I always let the car warm up to temp before any form of hard acceleration.....however i have noticed that if i do accelerate when cold ( just to see if its any different) it feels far more lively low down ( havent taken it fully up the revs) when cold. Could this mean its something that is not leaking when cold but when hot, expanding and leaking? My rocker cover appears to be leaking a little on the rear of the engine, front seems fine, could this be a cause?
For the previous post... I used EGR/MAF cleaner to clean the MAF, not break cleaner.
I have bought some carb cleaner today, will have a spray around the engine bay on Saturday when i start it from cold and when its warmed up to see if i can find a leak. Where is bank 1 lambda? Is it on the exhaust manifold at the front of the engine and as i have 3 readings on my delphi software does it mean i have e sensors?
I did 130 miles today and the car sounds lime its running really rich. Under hard acceleration it sounds very induction(y) but not much performance? Also the pinking noise is intermittent and does not do it when cold which makes me think its a vaccum leak and not a fueling/spark issue?? Bloody Fords....love it every time i drive it but gggrrrrr!!!
