both rears are set to "Not Reported"

 

thanks, in arlington do you have to do the obdII emissions?

 

ya man

 

i had a program running and i tested and it said not ready on 4 things, so my tuner changed them to non-emmisons in efi live and it still comes up as not ready. but 12 months ago with the same program it tested fine, the only thing changed was tire size.

 

Here's a good read from tech https://ls1tech.com/forums/showthrea...ight=o2+heater . Alot of f-body guys have the same issue. With headers there is no real cure I know of yet. If you search o2 heater on tech, there's a ton of posts.

 

If anyone is interested the new 02 sensor fixed the problem. The code hasnt come back yet.
