SOURCE: check engine light
you need to go to an electronic specialist or you can buy one of the scanners that clears the codes for you from advanced auto or autozone or some place like that.

Most faultcodes don't disappear automaticly, the have to be 'reset' manually after repairing. It sounds like the code didn't get erased after replacing the MAF. You could try to disconnect the battery for 10 minutes (disconnect and reconnect the negative (-) pole), which should erase the code.
Whenever the engine light still comes back on after that, there probably still is some (other) problem ...
