...wtf did you do?

 

[Lord Tin Foilhat]

no its that same p1133 code. usually a leak can cause it, but i fixed that and it seems to be the o2.

basicly the computer is either running the car to lean, or to rich at idle and isnt scanning like its suppose to.

i guess i could just take it to lattof, but i have no time. and if they dont warranty it, its alot cheaper to just replace an o2 myself, which is unscrewing and rescrewing

 

[wombat]

...okay

 

[Lord Tin Foilhat]

yep... this car is getting very annoying very fast.

im going to try reseting the computer tonight by pulling the power, maybe it just needs to relearn the new header/dp.

and i think i might go back to stock catback. idk anymore

 

[Lord Tin Foilhat]

and then to add to the top of that i think my exhaust is either leaking (catback?) or just loud lol. or its just my intake

Dont you have a warranty?

 

[Lord Tin Foilhat]

yep, i was just thinking that. just need to find the time to bring it

 

[wombat]

They might give you shit about it because they didn't install it. Just warning you. They asked about my pulley, but bryan didn't say anything so he warrentied it.

just because you have a code saying "O2 sensor low voltage" or whatever, doesnt mean the sensor is bad. there are many other things i would look at first before just throwing parts at it

 

[Lord Tin Foilhat]

its not low voltage. the oxygen sensor is having problem with the afr and switching it from lean to rich like its suppose to. it gets stuck at either lean or rich and doesnt sweep
