I have an OBDII reader and use it every time I get a CEL.

CEL codes:
Every few days I the P0410
every other week or so the P1411 shows up
today I got a new one: P0102

I've looked up the codes in the Bently, but it appears there is a lot of "Easter egging" to fix the problem. Previous posts say the 0410 is no big deal and will not not cause any long term problems, just poorer gas mileage.
P0102 - MAF changed out with OEM <10K miles. Pulled it out a few days ago and cleaned it. Not sure why this one popped up.
P1411 Secondary air injection system cyl 4-6. How do I figure out which of the components of the system is the problem???
