FPR, split hose, loose connection etc.

Got any more info champ? What are the car specs, how did you find out it's running lean on one bank, what were the specifics.

The more info you give the more useful the feedback.

All good, just makes things alot easier to help you out is all.

Also, which bank is running lean? Is it definately the entire bank, or could it be one cylinder on the bank.

Other things like, did you notice any power loss when driving or any symptoms, ie. why did you run the diagnostics check?

If its the entire bank it could be a fuel supply issue or an o2 sensor/ecu issue, whereas if its one cylinder it could be a sticky valve or dirty injector or something along those lines.

They hooked it up cause whilst driving the S# light stayed illuminated and the cruise light flashed. I threw it in for a service at a mates garage and he ran it for me. He's a great mechanic and suggested fuel supply and or dirty injectors. At this stage he suggested run some octane booster through and clean my AFM cause I was dicking around with it installing a new CAI. Otherwise he suggested poss wiring on that bank?? He says it's my turbo side? But I may have misunderstood. I will let you know tonight after I have dinner with him. Cheers pal.
