What exactly goes wrong with these in the j30 motors? My Acuras check engine light is on, and the code comes up for "EGR valve, insufficent flow". It is covered under warranty by acura, but I can never get the car down to the dealer, and a Honda dealer wont fix the problem for me.

Is there something that can be done with it? I know its right on the top of the motor, and pretty easy to get to... but what would I have to do to the damn thing to get it working properly again?

I'm asking here, cause I know certain accord V6s had the same problem.
