Of course it does matter. I was just writing to you that your mechanic seems to be treating the symptom, not the cause. I am surprised you did not have rough idle with that condition.
I would do the following.
1) remove the PCV valve and clean / replace and re-install. Make sure you order the plastic grommet with the PCV as it usually gets brittle.
2) connect the PCV hose.
Why would the PCV hose be disconnected all by itself ? I had a hard time to remove it from the PCV valve end
3) As you probably did not use the car for long periods of time, the fuel in the tank, filter, injectors got a bit gummed up. I would use a bottle of Techron (or Berryman's B12- Chemtool from Walmart for $3) and fill the tank and drive around as your fuel lines are cleaned up.
4) If your CEL does not go away, I would check for additional vacuum leaks, or fuel supply issues.
5) Clean / replace your MAF if you have not already done so, and make sure you clean the correct part two components (inside the tube, as well as the outside the tube intake air temperature sensor with MAF cleaner.
