Answer 1

P0155 02 sensor heater circuit malfucntion Bank 2 Sensor 1

P0173 Fuel trim malfucntion Bank 2

P0170 Fuel trim malfucntion Bank 1

How was the idle condtion.? Several area that needs to be check, one of them is the cooling system making sure there is no coolant leak . When t comes to a fuel trim malfunction this is mostly with the MAF sensor,  check the airduct of the MAF for any intake leakage that may have occured.

 Check the MAF airduct for any open that may have occured which does set fuel trim codes.
