Try spraying the sensor off with MAF cleaner. It can be purchased at Pep boys, Autozone. The can is grey and has red writing. It's specifically for Maf sensors. I keep mine nice and clean. It makes a big difference.
Could also have an O2 going bad. The idle problem sounds like a vacuum leak. Check your intake manifold gasket....with the car running, spray some carb cleaner around the intake manifold, places where it could be leaking. Listen for the idle to change....if it does, pay attention to where your spraying the carb spray.
