Lean bank codes normally point o a vacuum leak. Use a spray can of WD 40 and spray all around your vacuum hoses as well as you intake gasket. If it revs up or stalls out, you found your issue...

Your idle will seriously be affected by a vacuum leak. So, service, (test for) the vacuum leak first, the code may fix itself. Once you find the leak and service it, you will need to clear or reset the code.
