Have you actually tried changing the fuel filter?
Since diagnosing lean on wide throttle I've put one on order though.
Thats encouraging to hear. It would certainly be embarrassing if after all this the major power loss turned out to be a blocked fuel filter...trouble is I've had so many different and constantly varying symptoms that its been hard to pin down and separate them all. I have identified and fixed other problems along the way like definitely faulty spark plug leads, replaced a missing inlet manifold gasket, (both of which made a big improvement to a misfire) and (hopefully) fixed the gearbox problem with the oil. The symptoms have changed over that period of time but still the engine doesn't run well if anything its worse recently despite fixing some of the problems.Our V6 was once running a little sluggish and it turned out that the old fuel filter might of been blocked as the new filter made the car run massively better.
So here's hoping that a fuel delivery problem is the last remaining problem...and won't be too hard to find or expensive to fix... (Please don't be the fuel pump... )
