I got to the engine and cleaned the TB (didn't do the MAF because I realized I didn't have a security torx bit), reset the computer by disconnecting the battery, and was good to go.

Drove the car for another week and today the CEL came back - same codes. Obviously, the MAF might be an issue to look at, but what else should I be looking for? I tried taking the oil cap off while idling and it was really difficult - I could eventually lift it a bit and get a vacuum "hiss" but I cannot physically take the cap off with the engine running. Is this indicative of an issue? AOS?

Thanks for any help...

Get the proper tools (Torx) and clean that MAF. Go to Harbor Freight.

That tight oil cap... leads me to believe it is an AOS preparing to wonk on you.

Clean that MAF.

Or if you have a Dremel, grind some slots into the torx head and use a screwdriver to take them out.

I just bought a Torx set - I'll clean it tomorrow hopefully. Are there any other signs of the AOS? I get a little bit of white smoke on start up but no more than a few wisps and then none at all.
