Okay that’s good news, I thought I would keep you updated with my progress, the seller has removed the injector to find that the copper sealing washer is basically non existent, he has ordered a new sealing kit and is going to replace which will hopefully fix the issues, it is really difficult to fully explain as it’s not full engine misfire just a judder, I would say it feels almost like clutch judder. Needless to say I’ll be taking it on another decent test drive before purchasing it, in your experience is there anything that constantly makes it judder?
