W204 OM651 Knocking and running poorly
Story is it ran well until it died on the highway. I bought it as a project. Ive been chasing a nr 4 injector code (short circuit/malfunction) and I've now replaced it and recoded the ECU with it.
Now it appears to run smoother but it will still die sometimes just changing gears. It also sometimes knock pretty heavily like on the video.
Low pressure fuel pump produces 4 Bar steadily. Around 280 bar of rail pressure at idle. What more can I check and do?
