Alright I threw my first code today. I got it scaned and they told me it was a lean code and that my o2 sensor could be bad. I doubt that's it. It started when I put a breather on my manifold and disconected the tube from the cai and stopped it up. My modsare Injen cai, flowmaster 2.5, breather. I think it is just too high of an air fuel ration since the cai is putting alot more air into the blowers ince it dosn't have to share air with the manifold.

What do yall think? Should I dissconect the battery?

 

I get that code all the time, and so do the other redlines. I was going to put the breather on mine too, but was told it would throw the code. Ever since I got stage 2 I don't get the code anymore, by the way is the code P0171????

 

its the intake man. im nice so i wont get mad and tell u to do a search. but your intake is taking in to much air.

 

try the battery dissconect

 

Dude no one else has a breather on their car. I was just asking for opinions. I know what stuff has been posted a million times if I saw that others were having problems with the breather I wouldn't have posted here.

To all others thatnks for the input especially smokem

 

ok so if the intake is taking in too much air, how can u richen up the car so that the light will go off and stay off so it will pass an inspection, but i have noticed my MPG is amazeing now with the new intake

 

It is not my intake causing the light it is the breather. My intake never gave a cel until i put all air coming from it straight to the throttle body instead of allowing the cai to split it between the manifold and the throttle body.

 

ok guys, i threw the lean code on my 2006 cobalt Ls when i put in the AEM CAI.. ive posted this b4 but how fdo u guys get rid of it for good.. i called AEM and they said its getting air into it AFTER the MAF sensor.. so ive take it apart.. it goes off for a while than turns back on.. how the hell can i get rid of this for good.. will a reflash from gm be worth it?
