last night i tried replacing the wiring back into the loom on top of the engine and connector to injector 1, no better, tried number 3 which is a know issue for this engine, still no better, tried injector 2 and no better
although at one point one of the injectors made several large banging sounds but i didnt find out which one it was and couldn't repeat the sound will moving the wiring to the injectors about.
trying an ecu reset at the moment
car will drive sort off acceptably with lots of vibration and the turbo hasn't a clue where it needs to be - constantly open and closing of vanes on light throttle, so booting it seams to be the answer
I still think the problem is in the injectors not in a bent conrod etc but there's little point spending money now
