Hi, everybody
I have a LC 100 2005 with 230.000km on it and have had an issue with the slow response O2 sensor fault. I installed a new DENSO O2 sensor (the old one looked aftermaket) no codes now but bank 2 short term trim is -20 and the long term trim is +20 but only on bank 2 where the bad sensor was. No codes on the scanner the car drives fine I got 16mpg/17 liters on highway. What could be the problem here with only one bank running lean. I also cleaned the MAF sensor.
