code:001
246 Flow rate, secondary-air system, too low, bank 2
code:002
245 Flow rate, secondary-air system, too low, bank 1
After goes code 003
242 misfire cylinder 5
240 misfire cylinder 3
238 misfire cylinder 1
Misfiring probably caused by bad airflow by codes 246, 245.
What needs to be changed? Some body told me an air flow sensor, but I want to know exactly what sensor(s) do I need to change.
Thanks in Advace
