If I had an Increases Emissions message and there were no codes I would change the CCV valves as a first step. They are low cost and very easy to replace. They are also a wear item and will eventually fail so it's not a bad idea to change them even if they don't fix the Increases Emissions message.

Do a search for "increased emissions" , there are many threads with lists of possible causes.
Straight lines are for fast cars...turns are for fast drivers
