Help me
I am throwing two codes P0300 and P0130 one is random engine misfire and the other is HO2S Circuit Sensor 1 my car leans out at idle only when it wants to and the mv on the oxygen sensor will go down to like 50 or 60 ish and it will stay there is my sensor broken or could it be something else.

If the PCM detects the loop status is open too long, DTC P0130 will set.
If the Ho2 sensor doesnt heat up fast enough this code will be set.
Which could cause the mis fires as well because the pcm it not getting proper readings when the ho2 sensor is causing it to jump in and out of open and closed loop operation.
I would check and clean the connection first before replacing it.
