Did you keep your AIR?

You can either use sims for the rear o2's or have the error codes deleted by using LS1 edit or other computer tuning gadgets.
My air is gonzo.. and my car went thru emmissions no problem. Literally, once you get it tuned out, you will realize, it does absolutely NOTHING once a car has warmed up. And, if you changed the exhaust, went to longtubes, regardless if the Y has cats or not, they are so much farther back that the air doesn't work right anyway. RIP IT OUT< it is nothign more then 12 lbs of dead weight.
I too want to know if there are some photo's or removal instructions. Air and EGR are two seperate systems if I understand correctly, EGR on 1999 has a tube in top of intake manifold and the runs over to some kind of pump right next to the passenger side front of motor, so when removing this, i remove the tube, and the valve thingy, when removing the air, need to remove the pipes from the exhaust manifold, block openings, remove the pump under the headlamp, and the tubing running from pump to each side of motor.
Correct?

Def no regrets here!! Mine was the first thing on the to-do list when I did my header install. With all the ugly hoses gone engine bay tooks 10x better. The ones that keep AIR, you can probably count them on 1 hand! Ditch it, really no need to keep it.

I don't see how not having it could kill the cats...it only helps their efficiency when they are cold.
Now, if you send too much heat through them, you'll kill them in a hurry (hence why our PCMs have Cat Over-Temp protection).
Everyone should do like me and just reroute the AIR system back into the manifold. It is just like an electric supercharger, only you got one from the factory!
Routing the air system into the manafold.. probably not a good idea.
As for the system, it does tuen on and off while driving too, when the car's o2 sensors deem it nessassary for proper cat operation.
Bottom line... if you care about the envoirnment.. then leave it on. But, on that note, if you care about teh envoirnment, why are you driving a V8 car?
Rip it off, along with all the other emmissions **** If your car is bone stock, and you never plan to do anything to it, then leave it on, but if you are like 99% of the people with these cars, and 100% of the people ont his board and have done mods for performance, rip the junk off, it's only another thing in the way when working on the car.

Mine's gone too. I didn't pull mine until after about two years of having LTs on my 'bird, so I've got the block-off plates now. Appearance-wise, the block-off plates don't really bother me.....so I guess that's all that matters.

This is true if living in a state the requires inspections however if you dont then take it off along with the EGR and have it tuned out of the computer. As stated by other's, it cleans up the engine bay and gives much better access to work on things. Just my opinion.

now what i wonder is im in NJ and i have the sniffer does the AIR cause it to fail or does it only make a diffrence when cold. visual is not a big deal i have private shop do it and as long as the emissions pass they will pass it. so will it change the emmisions or no?
