Luckily most really bad failures look like really bad failures; oil dumping and bad noises. Post the codes on here. The emissions codes are usually an indication of a bad air flow or bad fuel delivery, neither of which are the end of the world usually.

I am no mechanic, but you have codes which are across both banks
possible causes:
a) bad MAF
b) problem with the timing chain ( read IMS)

Ok, I disco'd the MAF's plug, tried starting it, and failed. Replugged it in; failed. Am I misunderstanding the directions for testing your MAF to see if it's the missing link?
When trying to start it, it cranks, but no start. Keep the help coming...

When was the last time you changed out your spark plugs and coils? You should try unplugging the MAF and starting the car.

Tried; it cranked but wouldn't start. Spark plugs are 10k old, never changed the coils and have been driving it for about 25k miles. It has 92k on it now. Is it that time?

If you can tow it to Santa Clara, Marvin is the best!

I had over $3K done in work....would have cost me double that at the dealer and would have not learned a thing like I did with Marvin.

Ugh.
