I think you need to get yourself a Bentley manual to guide you in troubleshooting your problem. It seems as if you have a fuel related problem, but it could be ignition or even emission related. A fuel pressure test would be a good place to start, but dirty or clogged injectors could also be the cause and requires further testing.

No easy 'Just turn the screw to the left a bit' fix here. You seem to be replacing parts without testing or logic. Very expensive and (as you now know) won't fix the problem. +1 on the Bentley.

I've just changed my wiper blades and now my reverse lights don't work. Should I change my fuel pump relay?
