Sounds like it already is!

Have you got access to a Nanocom, Hawkeye or something similar? There might be some useful information to be gained there. Aside from that, I wonder whether it's an 'oil in the injector loom' problem? Have a look at that multiplug where the wiring loom goes inside the cylinder head and see if it looks wet. The other thing that could be causing poor running is fuel delivery. So (in no particular order) fuel filter, fuel pump, fuel pump relay and fuel pressure regulator. Are they working as they should, is anything leaking, could anything be introducing air into the system? Another avenue of inquiry is the air delivery. Hoses leaking or collapsing internally? MAF malfunctiong? Unplug it and see if things are any better. If so, its probaby gone wrong. Air filter getting full of dirt?

Another report of poor running I've seen from a TD5 owner turned out to be the timing gear - one of the sprockets had moved round slightly on its shaft. But try the cheap an easy things first that don't involve dismantling the engine a second time.
