Associated effects of these codes are:
1) Loss of power
2) Poor MPG
3) idle issues (normally when starting up)

Now to see what is the best way to fix this problem.... BTW this forum is GREAT!
Those codes can be a number of things related to anything from o2 sensors (but not likely) to plugs, MAF, air leak in the boots, etc. I would check everything that applies.
