Ok chaps, all my rough running issues have been addressed, 6 injectors, wiring loom from the scv's, new EGR valve and all the inlet manifolds thoroughly de-cocked has left the old bus running like a dream, and back to full power again.
However we still have the vibration at idle and a rumbling from the gearbox that i can only assume are linked, i think either DMF/clutch CSC or even a shot bearing on the gearbox idle shaft. 2 questions realy, any thoughts?... and are the f40 box's from the 1.9 the same as ours. I can find a 1.9 box no worries, however ours seem to be like rocking horse manure....
All thought gratefully received..
