Im new to this forum so thx for letting me be apart of it. I have an 06' Z and my primary 02's on banks 1&2 are throwing codes for some reason. I have a Injen intake, MrevII Plenum w/ 5/16 Spacer intake side. Exhaust is Kinetix
test pipes and HKS Dual. I cant figure out why its throwing the codes for the primary o2's when the mods i have done have nothing to do with them !!

 

Your test pipes are what's causing you to throw the codes.

Sorry but this does not help me out cause ITS THE PRIMARY O2's the HEADERS not the test pipes but none the less still good info thx

 

Also i know im being a little harsh sorry but im so dam frustrated with this problem cause i don't want to go to the dealer so solve this

 

Oh, my mistake. I just quickly glanced over it and saw that you had test pipes, so I figured that's what it was.

I think it may help if more info was given. What were the exact codes you're throwing? When did this happen (after or before something happened)? What's your current mileage and condition of car? Any additional info may help others troubleshoot your problem.

 

K cool thx it was 28 500 miles on it no accidents the SES light came on shortly after the plenum and spacer were put on. The HKS and test pipes were not installed yet thats why this makes no sense to me about ti being the primary O2's

 

the codes or P2A00 and P2A03

 

Will a dealer work on an obviously emission tampered [test pipe] vehicle, most won't for fear of being classified/charged with "aiding in felony tampering" some time in future. Depends on your STATES enfocement of Federal Laws.

Air leaks in aftermarket plenum/spacer resulting in leaner than expected conditions?

 

Different codes, I'm on 2004.5, but this might be of some help.
