Okay troops..... Pootling around the A2 runs nice... As soon as you give it some the EML flashes....... VCDS lite says now multiple misfires and cylinder 2 but I redid the earth node so that maybe the multiple sorted as might need to crimp tighter??
Is this a potential carbon or fuel pump issue...... Plug swop showed 1,3,4 running cleaner but 2 a bit sooty????
Maybe the diagnosis of injector was accurate??? I've put redex extreme on now in attempt to clean fuel delivery and injectors with 98 fuel???
