Hi. Please can anyone help? Im having problems with my Ford Focus 1.6 TDCi which seems to judder as if it sounds like a misfire, whilst in idle speed and in acceleration. I recently had a leaking fuel injector, which I had repaired. Hoping that the repair went well, this new problem arose and I cant seem to identify what this problem could be. I took it back to the garage and they said that it could be cause of the carbon built up within the fuel systems from where the injector was leaking, and nothing even came up on the diagnostics. Just now, I started the engine, ran smoothly, then the judders began, so i gave a few revs and it seemed like there was a sound of misfire. after i let go, the car just switched off. i tried turning her over again, switches on, then dies out. i waited a while after, tried, still no luck.

Is there anyone out there that will be able to identify what this fault could be?

Thanks
