Service Engine Soon Codes Looking to delete my EGR and AIR anyway, but what do these codes mean? Some are part of the AIR system, which is going to be deleted when I install my new Lid and MAF. EGR will be deleted if I install the LS6 intake.
5 Codes Total, that I know of. I jotted them down as the guy at the shop read them off to me:
1.) E0300 - Multiple Misfire?
2.) P0410 - Secondary AIR Injection
3.) P1415 - Secondary AIR Injection System Bank 1
4.) P1416 - Secondary AIR Injection System Bank 2
5.) P0305 - Cylinder 5 Misfire
Perhaps you guys can help me out here. Is the AIR system already deleted, or malfunctioning? Could some plugs and wires help out with the misfire issues? Misfire isnt noticeable, just kind of a little lope at idle, but the RPMs are consistent at around 750.

It doesnt effect drivability or anything. Just concerns me because I know it isnt good to have a misfire. But there is no bucking or jerking, just a slight "lope" at idle. Still idles perfect at 750, no fluctuation.

Wondering if anyone can help me out?
Ive got a 2001 camaro ss and I'm getting p0410-Secondary Air Injection. I just replaced air pump and check valves will be next. The weird thing is that code is only pending until I turn on the A/C it becomes stored. Does anyone know what A/C might have to do with the code , any specific vaccum I should look for to see if leaking?

The ac is loading the engine and taking power,, I'd start with making sure the ignition system is getting full power. I'd start with check the alternator battery etc. A bad battery + a high output ignition system can cause some bizarre engine issues..
