I assume there are no other symptoms that may be associated?

Can you check for fault codes? That would be my first step. If no fault codes---

I would clean the MAF sensor with MAF cleaner. Very easy,inexpensive to do and a good idea to do once in a while because it is part of controlling fuel/air mixture and can be the source of problem you are having.

I would do have a pressurized smoke test for vacuum leaks after checking visually because vacuum leaks are frequent causes of engine issues. I seldom am lucky enough to hear or find a vacuum leak. A smoke test wipes that off the list or finds it.

Then I would check to see if the CCV hoses are clogged or restricted because the more miles driven the more likely it's happening.

There are other potential causes or approaches. I think these are a reasonable course toward pinpointing the problem and are easy on the budget.
