Funny noise post CAI etc

Just joined the forum although I've surfed it from time to time. Working on a 2000 LX 1.8L . Put in an Injen CAI and get an intermittent clicking sound that I can't locate. Seem to recall someone said somewhere they have heard of this. Any idea if this can be remedied? Also get a cat error message from the DTC which I also believe is related to the CAI. Again, any remedies to correct the error?
