Review on Kwiksen 2Pcs Upstream And Downstream Oxygen Sensor 234-4205 234-4061 O2 Sensor 1 Sensor 2 Compatible With Corolla 1.8L 1998 1999 2000 2001 2002 by Jeff Davidson

So after changing my Upstream sensor on my 2001 Toyota Corolla LE automattic it resulted in a pain in the behind clip that you have to compress so clip in and after changing my car started to sound different before with the other sensor the car didn't make any erotic noises when you applied the gas pedal and the little gasket that came included was a POS thing I felt that there was a exhaust leak cuz I can smell odor coming out the pipe so what I did was I took out the auction sensor replaced it with the old heavy duty gasket and plug it back in and the oxygen sensor code disappeared but now it tells me that I have a po171 bank 1 system too lean? I have asked the community does the spit and work perfectly on a 2001 Toyota Corolla LE automatic they said yes but I'm asking you the maker of this product does this thing work?
