Hi, Hope someone can shed a ray on this one.It came in with a complaint of "chucking",it was a while since the last fuel filter change so i started there,the diesel was very cloudy and murky so i drained the tank and filled with fresh diesel. After this it was still chucking,what feels like a bad misfire, so i did a code read and i got the usual code for the injector loom so i fitted a new one and cleared the code, the injector compensation values looked good,but the chuck is still there.While test driving i stopped and unplugged the air flow meter (don't know why)and although it was down on power,the chuck or miss was gone,i tried this several times with the same result.I scoped the AFM and its giving 4.3v. I cant figure out why the chuck or miss disappears with the AFM disconnected.My code has not reappeared and i only have a code for afm as its disconnected. I am a bit stumped and lookin for any ideas.
