According to google it's a 'misfire excessive emissions' fault, but doesn't say that it's a direct result of some failed component. Though if I had to guess I would bet on O2s... Can you deal front and rears to see what happens?
Since you've already cleaned the Maf and done the ignition tuneup.

To find out if it is a sticky exhaust valve you will need to run a compression test.
Then if it turns out to be a sticky valve you have a couple of options.
Tear the engine apart and clean it.
Or use a high detergent motor oil and do a couple of "short" oil changes.
If it continues after that then I would add some MarvelMystery oil or Seafoam to the crank case and run the hell out of it to break up and remove the sludge.
