![Question](https://my350z.com/forum/images/icons/icon5.gif)
So I posted yesterday related to my low idling problem but I have new information, on my way home it threw P1167 "Heated O2 Sensor (b2)" so is this related, possibly? or nah? I have a z1 intake and here is the rest of the info on the problem but when the new maf comes im gonna try an idle relearn and throttle relearn and ill see from there
Ever since i bought my Z i’ve noticed some low rpm’s at idle (400, even 350 sometimes) this happens when i’ve warmed up the engine a little bit and and i come to a stop and put it in neutral and then rpm will drop.
when I put it in neutral and the rpm’s drop it will do 1 of 2 things.
1.) It will just drop to below 500 and stay there or
2.) it will drop really low (sub 300) and then bounce up to sub 500
the most concerning part of this is the fact that i’ve had it die on me while driving because if i’m really hogging on it and then have to suddenly stop and put it in neutral it will drop so low that it dies

Yeah im making some progress. I dont know if i mentioned this in my original post but I also have started to have a problem with the car stalling on warm starts. Many other threads with this issue has led me to a simple throttle body clean out and all the appropriate relearn process should fix this. Back to the original issue of low idle, i have now gotten 2 codes P1283 (idk what this one is besides some upstream o2 sensor alerting a lean A/F ratio). The second code is P1167 (heated oxygen sensor 2 bank 2, which is driver side i think) So I could have an issue with the test pipes and o2 nonsense but im gonna start off cleaning TB and relearning and ill see from there. I am already running defoulers with my o2 sensors and my test pipes so idk.
