How to tell if M.A.F is good?

[mike87we4]

Hello guys, a friend of mine just gave me a M.A.F sensor off his 96 impala ss engine. The engine was sitting for about a year, is there a way to check if its working properly? I just ordered the new MAFT GEN II translator from fullthrottle, and i was wondering if i should of ordered a new MAF.
