I replaced coolant temp sensor,brake vaccum pump,air filter and cleaned the mass airflow sensor.And reset CPU by disconeccting the battery for 30 min. Check engine light is back on po171 bank 1 system too lean shows again. My car is idling @800rpm and shuts off sometimes. In addition EPC warning light appears and rpms go up to 1100. O2 sensor,Mass air flow or Major problem?????????

Default System too lean could be from a boost leak assuming 1.8t

Check all the vaccuum hoses for rips or tears; they tend to deterioiate after a while
