1999 Chevy Lumina 6 cyl Two Wheel Drive Automatic

I used an OBD II and got a PO102. It says MAF Sensor, but replcing it didn't solve the problem. The engine sometimes runs choppy when I go from highway to city. It settles when I put it into Neutral or Park, at a light of course. Any suggestions?

Check for any air leaks at the MAF sensor, throttle body, intake manifold and check out the PCV and EGR systems. Make sure there isn't anything clogging up the passageway for the MAF sensor inlet and duct work.
