I initially pulled up code P0171 bank 1 lean and my mechanic replaced both oxygen sensors. after a few days the service feathery came stern on, so he replaced the catalytic converter. now the street lamp is back on again. The coup¨¦ runs great but I'd like to know whats wrong and fix it.
Answers: low fuel pressure or volume will create a lean condition check fuel filter make sure it is not blocked and testing fuel pressure and volume
Could be as simple as a vacuum leak but the converter might own been beneath warranty, check your owners manual.
