It would be interesting to see if Autologic comes up with faults that other scanners do not see. Quite often we see vehicles that have done the rounds & are able to retreive fault codes that others have not been able to, your problem I would sugggest is most likely to be an injector & should show up under compensations.
Where abouts in the country are you ? I will see if there is a freindly Autologic user near you.
