Re: system to lean bank 1
i had the same code a while back, look under throttle body right in front, there will be a rubber elbow, about 3/4 inch in diam. that rubber elbow is replaceable, mine had a hole in it, if that isn't it, run your engine and feel around all the vaccum lines, mine also had a hole in a line coming from pcv valve to the back of throttle body, i just went to local auto parts store and bought some vaccum line and replaced it, it cleared all my codes and havent had any trouble since, thanks i hope this helps.
