Have a T4 1998 1.9 turbo diesel... although I might as well not have a turbo!
Very slow and starting to struggle finding out why.
Fully qualified tecky and m.o.t tester with all equipment available.
Turbo waste gate is fine and turbo is not siezed.
Timing is correct as I thought it may be retarded but have lined everything up with correct timing kit.
Fuel filter has been changed.

Next thing is a leak off test on injectors but not very optamistic about this!
Any known problems people? Thank you!
(Apologise if this thread is in incorrect place on forum.. cant use forums for s*** lol)

I realise you are way more qualified than I this, but from what experience I've had on 1.9td t4s with mates, new throttle cable and air-filter can make a genuinely huge difference.
Having looked at bigger picture stuff on one van, both these transformed it in the end. Cable alone made a big difference on another too. Probably all sounds simplistic, but....
