Hi, do you have any codes? Without codes it will be guessing,,this looks like incoming
air seeping in after the Maf sensor,check for cracked hoses and the pcv valve and
surroundings.

The codes refer to a system too lean in bank 2 and overall the system, this can be
caused by a bad maf sensor or electrical connection, or a bad connection around the
maf sensor, check clamps and intake hoses.
