I put it on the scanner and and it showed o2 air fuel meter bad. I buy this part from Toyota dealer. Make road test and go back and the same problem o2 sensor bad. I reset the computer also remove the two parts that I installed and starter the engine to make sure is not plugged. Everything look ok. Put back the sensors and the problem persist. I drove the car for 55 miles and was ok. I turn off the engine but when I turn on and start driving again, the check engine light came on and show problem with 02 sensor.
