Evening all,

Range 4.2 sc the big girl has been running great! think I’ve broken the back of most of the issue I had with.

Ongoing intermittent issue of the lean bank 1 and 2. So I’ve now realised it’s happens like clock work after refuelling. Usually the day after refuelling I’ll get the code but a day or so after it’ll go off again. What I’ve not managed to work out is if it’s fuel level dependant.

Originally I thought there must be **** in the tank which is getting mixed about when filling up but now ism thinking it’s something else. Is there anything in the tank or in the fuel
System itself that would cause an issue like that?

Car never struggles to start or hesitates/stalls

Thoughts
