Heres the list-
P0443, EVAP Canister Purge Control Solenoid or Valve Faulty.

P0135, Upstream Heated Oxygen Sensor Heater circuit fault - Bank No. 1.

P0136, Downstream Heated Oxygen Sensor circuit fault - Bank No. 1.

P0141, Downstream Heated Oxygen Sensor Heater circuit fault - Bank No. 1.

P0155, Upstream Heated Oxygen Sensor Heater circuit fault - Bank No. 2.

P0161, Downstream Heated Oxygen Sensor Heater circuit fault - Bank No. 2.

P1409 Electronic Vacuum Regulator Control circuit fault.

Would bottoming out on the midpipe cause all of this? I can change the o2 sensors but have no clue about the EVAP canister or the EGR circuit. Thanks for any help
