96 Camaro v6 3.800

My car idles a bit high.. It idles at 1500-1700 RPM's depends on the move she in in... The check engine light is on it reads Mass Airflow Sensor. I have replaced it. Also EGR valve. I have replaced that as well. Brand new parts. I have disconnect the neg battery for 30 mins and the light still pops on! I check for vacuum leaks. Is there anything else that can be wrong? Possible bad computer?

Please help!:crying:

Ok check the connection (male side)at the MAF sensor. It could have corrosion or something else that will prohibit a good connection. Check also for any breaks in the wires going to the MAF.
