2007 Toyota corolla has a brand new air filter, pcv valve, and mass air flow sensor and runs great until the car is warmed up and once it warms up the rpms jump between 500 and 700 rpm until the car shuts down. Not sure what to do next.
Possible faulty connection however all the connections look good. Only does it once it warms up and switches to an open loop where sensors are checked.
Possible air temp sensor???

Vehicle: 2007, Toyota, Corolla
