Questions before I spray. Ok well everything is up and I just want to make sure I am good to spray.
I have to following DTC's.
P0412 --Secondary Air Injection System Switching Valve A Circuit Malfunction
&
P0418 Secondary Air Injection System Relay ‘A" Circuit Malfunction
Should these be fixed before I spray? Wth are these? AIR or EGR or o2 sensors???

shouldnt be a problem, those are for your air system that only comes on for about two mins during start up to help with emmisions, if thats all thats holding you up, I say spray away. Did you delete your air system or take the relay out?

Nope, even when it was hooked up, it only sprayed extra air into the exhaust to help heat the cats to their optimum efficiency, it doesnt inject air into the engine at all. You'll be fine

As everyone always says though, makesure you can verify youre air/fuel anyway when spraying. Just incase something else is wrong and causes you problems. not trying to scare you, just saying. I remember the first time I sprayed, it was at the track and I was scared I did something wrong and was gonna blow it up in front of everyone.

Removing A.I.R. mostly just cleans up the engine bay but if you take away the EGR you will have a new issue with detonation. Modern EGR does not adversely affect performance. In fact, EGR controls the flame front and allows for more timing. EGR is not just an emission thing any more.
