    Expect the thread to be closed as we dont talk about Op-Com

    But atleast you found 'the right place to ask '

    TBH he's not discussing opcom. He's asking about figures that any decent code reader could read.

    Can't tell you what the figures should be though mate sorry

    Ah cool,

    From what I remember upto + or - 10 is acceptable (As close to 0 as possible) but as you can see 1 and 4 are wearing more than the other 2.

    Maybe stick some inj cleaner through as that bought one of mine that was at -7 back to -1 on my 16v CDTi

    Wait till others can give values but you might just be able to get them cleaned/checked.

    Is it causing a running issue as the values look to be within spec.

    This thread suggested that the readings should be between -3 and +3:
    http://www.vectra-c.com/forum/showth...=116974&page=4

    There are some over tips in that thread like changing the injector wiring and checking the injector seals for leakage.
