Selective Mass Adjustment

blucoop · 07-05-2014, 08:23 AM

Hi.

I have got a rough and noisy idle on my 330d and what feels like an occasional misfire.

I have had all injectors sent away and tested and all are fine. one came back with a different code but this has been corrected.

I have however looked on INPA and my Selective mass adjustment values are as shown in the pic.

Can anyone shed any light on this as Ive done the research and all points to injectors?

Any help much appreciated.

thanks

Looks like excessive correction on cyl 1.A leak test would confirm this but unlikely you'll get you're hands on the gear to do it.I would be looking at an injector or double washered.
