I I have a ML 270cdi and it I idles terrible. Just moving around from 700rmp to 800rpm.like it doesn't want to run. Also it feels like it's going to conk out sometimes. It's an automatic 2004 done 125k miles full service history. It's only started doing this. Otherwise has been perfect for me for the last 4 years. I was thinking a couple or just one injector problem or a fuel problem. Any1 have any idea's at all please?????

You need it plugged into a Star firstly.

That never seems to work for me, did get this done and came up no faults

Live data is the key. Fault codes are only a little bit of the info.
