yea so i was coming home from a getting a haircut and it just randomly popped up. so me and my dad took it to autozone to pull up the code. i dont remember the code exactly but it said i was running lean and needed a new o2 sensor. so tomorrow im getting a bosch o2 sensor to fix it. just thought id share.

Did it mention which O2 sensor? cause I remember a member on here said he had a code like that and he just removed and it cleaned it off and it worked find. . . it was just kind of dirty

bank 1 i think he said? im pretty sure it was the main one. the sensor itself was near the headers

i got p420 for a while.. the 02 sensor in the exhaust pipe. I got the code repeatedly for i'd say twice a week for a good month and a half. after resetting it and resetting it, it just disappeared

^^^^ That person was me, but it was right after I installed the exhaust, disconnected the battery also for 10 minutes and let the ECU reset itself while I was cleaning the o2 sensor.......
