still have cel even after o2 sim
ok so i bought 2 o2 sims from casper electronics to replace the 2 rear sensors on my new header and "y" pipe. i had the cel cleared and it stayed off for about three days then came back on. now originally i got 2 codes p0420,p0430. which are the 2 o2 sensors post cat bank 1 and bank 2. now i only get p0430 which is the post cat sensor bank 2. has anyone else ran into this and why is it only the one? i know a lot of you have put on headers so i'm hoping you can help! thanks!

I have heard of the sims being very flaky and that they have a tendency to fail.
There is another way. Install spark plug anti fowlers in your y pipe then plug in the o2s into those. What that does is makes the sensor probe go not as far into the pipe which emulates cat temperatures. It's popular with imports.
