Morning all, My 2010 Cupra was having issues last week with engine juddering, due to the famous engine misfiring issues. The fault codes were for multiple misfires on cylinder 2. My garage went ahead and changed the spark plugs and coil pack. This seemed to fix the issue for about day, and now the check engine light is coming on again and the juddering is even worse than before. It seems to be about 4,000 revs when driving hard, but not always. There doesn't appear to be any smoke or any whine from the engine, it just kinda judders and loses power for a moment. Any clue what could be going on here? Thank you.
