I have seen the rubber weatherstrip at the rear of the hood and cowl drain hose plugged or missing cause this. Water will pour in on top of the motor and get down inside the spark plug tubes. You may find rust and white powdery corrosion left behind from the water when you pull some plugs toward the back of the engine.
There is a couple of PCM flash updates for setting false O2 and EGR, etc. fault codes. If you are under 80K, this may be covered by your federal emissions warranty. The latest and greatest PCM software would be desirable. Has the cluster recall (G07) been done?
