The 02 sensor just monitor the engine condition, The ECM uses the 02 sensor for fuel control, When the vehicle stall in park you have a IAC (idle air control) problem

Also check the pcv hose as it is common for failing back at the throttle body

Could u tell me the part number for the pcv in my car, auto part gave the wrong one. Should I put a clip on the hose at the throttle body to keep it steady? Thank you.
