During the autox the Nissan Quest did a combination of sounding louder, like intake noise and down on power.

It's throwing the codes P0011, & P0021.

What does the hive know?

Sounds like vtc failure.

Maybe it oil starved. Sometimes Subarus will throw variable valve codes when they get low on oil in transitions.

Time for a mild overfill and ECU reset maybe?

Those are the same codes my 04 Forester XT threw when it decided it wanted an oil change. I agree with ssswitch, top off a bit high and reset ECU.

It's toast. Dropping the body onto a Q45 should fix it.

Low oil pressure to the VTC system. Check your oil level. If it's good, mechanically check oil pressure. If that's good, then you may have a blown gasket in the timing cover where the oil supply to the VTC sprockets runs.

Now I know why it ran a 20 ¼. OK, check the air filter housing to see if it came loose. I know this sounds strange, but I've had it happened on a HHR that was being driven on some bad roads. It sounded louder, ran horribly, and shifted worse. Somehow the jostling had disconnected it from its mount on the intake.
