Over fueling fault chasing
Discussion
Good afternoon all, seeking advice / experience on chasing a clear over-fuelling issue (sickly rich smell from passenger side exhaust)
Diagnostics output of a cold running below (I’m hesitant to run too long and up to full temp for fear of ruining the cats)
To me, diagnostics are showing clear delta between banks on lambda and adaptives. Adaptives are hugely in the negative, suggesting to me unburnt fuel.
I haven’t looked at plugs or swapped plugs, injectors or lambda sensors yet. (That will clearly be my next job)
I’m questioning myself if this is a lambda fault as the trace and difference between the banks looks very odd to me.
Thoughts / options / experiences?
