Your tune could be off, your O2's could be shot, you could have vacuum leaks, could be a number of items. If possible, hook up with someone with scanning software and take a 20 minute scan-log to really pinpoint the problem.

Anything is possible, but I would think it unlikely to be in the tune of the car was fine for a year prior to throwing the codes recently. However, being that you are getting both banks coming up rich does make unlikely that both 02's failed at the same time though.
If you would like to set up an appointment to have have us take a look at it just let me know, I'll be happy too.

Thanks guys, thought the same thing about the O2s both going at once. Took the air filter and MAF sensor out today and gave it a good cleaning. Will give that a try, they were both pretty dirty. Doug thanks for the great customer service as usual.

Any time, one thing though, a dirty MAF sensor will cause a lean condition, not a rich condition.
