Hi another day another problem, been chasing a misfire since I got the car only under load at 100% throttle between 1500-2300rpm egr off dpf off new clutch and dmf new crank sensor it is quite violent very noticeable, done some data logging and fuel pressure looks ok desired to actual only thing i see is injector 1 has a much higher injection quantity correction can be as high as 1.2
Anyone else had this issue?
