Ok so over the weekend i converted my Lx exhaust to a Ex same head d17a1

now the cat from the ex was oem i used a dc carb legal header

now here is where my issue began

everything fit perfectly but im throwing 2 code

1st code : PO135 O2 heater circuit ( bank 1,sensor 1)

2nd code : PO141 O2 heater circuit ( bank 1,sensor 2)

now from the lx o2 sensor need extending so i did so

first i crimped them made sure to use the wright gauge wire and everything this still gave me these 2 codes even when turned off they would still pop back up

second try to fix it i sauterd the wires makeing sure each wire was where and how it should be connected for proper conduction and protection from the weather aka water

i still threw those 2 codes

after i turn off/erase the codes wright after starting the car the check egine light pops wright back up **like its mocking me *** grrr

so wright now i cant pass california smog and my car is possibly running rich

also i would think i should go into limp mode and i have not weird

i have a lx ecu and im thinking maybe this is the issue im realy dunno at this point thats why im asking for help ideas to fix my issue or anything to test for

thanks honda-tech and the 7thgen community for any one that tunes in and helps me out to fix this issue

also the o2 sensors are like brand new 100 miles on them bosch
