Cel! P0411
hey my car has a check engine light for P0411 for secondary air injection incorrect flow. only mods i have is RB header, high flow cat, RB catback. Anyone know anything about the light? if its a valve or anything else cause i hear like a valve click on then the engine will sputter alittle. Please let me know if you know anything.

2nd time I've heard of this code for someone who installed an RB header. Not sure that it's the same because the other guy did an AEM CAI at the same time.

I have the RB headers, high flow cat, and RB catback without this CEL.
Did you disconnect the air pump and not plug it back in?

^................. or see this thread for another idea or take on the airpump. I know yours is an RB header and the other is an OBX, but can't hurt to make sure the gasket has the needed holes!

Note that one guy apparently had a loose air pump hose on the new header as well.

are you guys sure that the obx headers with holes to hold air injection has actually notch ine the big hole to gives air to the other? because i have them on my car, the dealer installed them for me and installed the air injection hole, but the big hole was all dark and we didnt pay atention to these notches in the hole.... so they just disconnected the air pump in the engine bay! i do have this p0411 code running and am running some problem right now....

yeah i have checked the piping and the connectors everything is hooked up properly cant seem to figure it out let me know if anyone knows how to solve the problem. cause ill drive it for a few days the light will go out then start it the next day and it will come back on. the dealers are trying to say they think its the header and they dont know anything else.

its because the air pump doesnt give enough air to the cat! u should put back your stock manifold or put a catless mid-pipe, cause it will kill your cat in no time...trust me on that!
maybe holes in rb header are not big enough to supply enough air from the pump!
