reseting the engine check light

True,

but when you get readouts on both cylinder banks at the same time I usually first suspect a problem which affects both cylinder banks. It's less likely that Oxygen sensors on both sides die at the same time and more likely that one COMMON component bit the dust. The MAF might be the culprit here...

There are many threads about diagnosing an fixing MAF related problems, simply search the forum for MAF

For more information on CE light codes, check the page on my web site. I have them all listed.
