Try one of two things:
1) I'd bet money it's the RCM. Stop throwing all this money at it and order a new RCM and see what that gets you.
This will cost you around $150 and you can replace it yourself in a few minutes. Even if DJ did the "rebuild", you could have a sluggish relay or a bad solder connection, it happens.
2) Ignore the CEL. The secondary air injection does nothing but help heat up the CATS in order to make them work faster and better. It does not make the car run any better. Unless you are trying to pass an emissions test, you can ignore that code. Iknow it's annoying, cause with that light on you dont' know if its a 410 or some other, more important code.
