Not always. The first thing I'd do is check for any DTCs that may have been thrown.
Cleaning the MAFs is very easy - two screws and the MAF slides right out, spray it down with cleaner, let dry, re-install, do the other side. Takes less than 5 minutes per side. Considering all the problems MAFs can cause and how easy they are to clean, you might want to clean them once a year - or every oil change if you're real finicky (but that's probably overkill).
