Oxygen sensor/s went bad in my TJ a few months back, had them replaced. The codes poped back up and the problem is back. Mainly chug when in park and idiling, or when foot is on the brake stopped while in drive. Is somrthing making the sensors go bad? I dont want to replace them again if they are just going to go bad again. Any suggestions? Codes I read are below. Also could use some hellp identifying what sensor I need to buy and where it is located.
P0138 - O2 Sensor Circuit High Volts (Bank 1 Sensor 2)
P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
