Figure out my code problem
I need some ideas as I've run out. I keep getting p013a and p013e codes. It says downstream o2 slow response blah blah blah. The car has a catless downpipe on it, and has had it for 1.5 years but just started throwing codes the last 6 months. I replaced the 02 sensor, checked every inch of the exhaust for leaks (none), and tried a o2 simulator. Nothing seems to change anything. I can turn on the code scrubber on my jb4 but I want the car to pass the emissions readiness test so I don't have to rush to solve this problem when I have to get tested for tabs later this summer. Any help would but very much appreciated.

Try factory oxygen sensors and retest. If that fails, swap back on the stock downpipe.
