Need some help from experienced members. Listed above are codes being thrown by my car.

Some background: '99 ES 300, 195k miles.

All four codes are related to the AFR/Oxgyen sensors located before the catalytic converts on my car. I replaced both sensors with correct Toyota parts. Same part numbers, no half assing on that end. I cleared the codes and within 20 minutes of driving they are coming back.

Now, before I replaced the senors, the car couldn't get out of it's own way. It literally putted along @ 2mph to get it to a parking lot. Now, after the sensors it drives super smooth. Idles nice and "appears fine" driveability wise. The issue is the check engine light and why it won't stay off.

1133 AFR, Bank 1 Sensor 1
1135 Heater Circuit, Bank 1 Sensor 1
1153 AFR, Bank 2 Senor 1
1155 AFR, Bank 1 Sensor 1 (same description as 1133) WTF
