2004 toyota camry Le 2.4

I’m having a code p2238, when I start the car it starts fine then goes rough and i can hear some sounds like it wants to stall. Any help will be appreciated thanks

That code indicates a problem with the heater circuit for the O2 sensor for bank #1 sensor , #1 sensor.

Usually caused with the failure of the heater within the sensor.

Will this cause the engine to missfire?

One of my coils is bad, that may be why the other code came on

Replace the coil and see if the other code goes away.

That is what I will do, I’m waiting for one coil since we have another vehicle. A good coil runs around 90 dollars but online is half price
