Using a ELM scanner(cheap scanner and notebook pc) to connect I notice I have +12% avg on the Bank 2 Long Term. Which means a little lean on bank 2. Possible vac leak. Also the EVAP Monitor never completes. The CEL is off. Should I not worry till the CEL is on or should I try to get the Bank 2 Long Term and EVAP monitor to be right? Thanks, Pete

If you can, it is always better to nip any problems in the bud.

Is it possible the two issues are from the same problem? How can it be lean on only one bank? Where do I start to look for vac leak? Do you have a guide for the EVAP system? Where is there a potential leak location on only Bank 2? I thought both banks are connected intakewise. Thanks

Some vacuum connections are nearer bank 2 so these could be the cause. There are no guides for EVAP systems available. Mostly these monitors are completed after a certain drive cycles and if any problem persists, or some driving conditions not met, they would not complete.
