Need help please
Hello
I have Lexus es300 model 2000
The problem is that I feel my car very slow and its acceleration is very bad.
I replaced many things but I still have the problem
I removed catalytic converter
When I do computer check
I have p0420
I think I have oxygen sensor problem
But which sensor it is?
There are two
Please help me

With slow acceleration and a P0420, I'm willing to be you have a clogged catalytic converter. It will be loud, but you can test it by removing the upstream O2 sensor(s) and driving it. If it accelerates normally, you have a clogged cat.
