Yes, The MAF is the plastic piece clamped into the tube going to the engine. There is an electrical connection the goes to the MAF. If you remove the connector the idle RPMs should increase. As an example, if current idle is 500RPMs and the MAF is working you will hear the RPMs go up some amount say to 600.
The MAF contributes to the fuel/air ratio. When the wires in the MAF are contaminated it will cause symptoms such as yours. If the MAF hasn't been cleaned in 30,000 miles I would just buy the MAF cleaner, remove the MAF and spray the wires until they are clean and reinstall to see if that helps.
