Another p1135 questio

Hi Everyone
I have been doing a lot of research on this code and I am confused on one thing.
So I have a 02 3.4 4x4 185xxx miles with a p1135 code. So I bought the upstream air/ratio brand new from Toyota stealer ship lol... last year along with the Urd back sensor simulator and code went away for about 4 months. Then, it kept coming back ramdomly and now it won't go away. I used my scanner live data and it's telling me that timing is advanced in cylinder #1. Also, I just replaced the catalytic converters last week in hopes to eliminate/help with the problem with this code. The pre cat is authentic from a very low mile Tacoma 30xxxx from a Tacoma I had years back. And the main cat is a brand new aftermarket unit I purchased from eBay for a Tacoma with the same specs. So my questions is can advanced timing on cylinder 1 cause p1135, Id hate to think that the original sensor may be damaged in a little less than a year ?
Thanks in advance for any help. Oh almost forgot I did check all wiring.
