Throwing both codes after a 45 minute ride home from work yesterday where it idled and took off just a little rough. The light came on this morning and I checked it.

It's got 146k but is spotless... inside and out. Under the hood is in perfect condition with very little signs of age.

I'm going to run some Sea Foam through it and see if that helps. Then maybe plugs and wires? Any other suggestions?
