Is this injector correction normal?
I sense a very slight hesitation or vibration in my 147 Jtdm it's not much different from normal diesel vibration just at higher revs and I don't think was there previously. The car has been serviced recently and nothing was found that is wrong - no error codes and no obvious faults. I've connected ECU scan and comparing the correction values for the injectors no 3 seems to be different from the others, see the attached file.
The range seems similar to the others but it looks as if the track is often moving in the opposite direction from the others, see the trace from 945 to 1020 on the bottom scale. I don't know enough to know whether this is normal or indicates a problem. Could having the injectors cleaned help if it is a problem?
If anyone out there in diesel alfaland can tell me whether the trace is as expected I'll stop worrying.
Thanks in advance
