After listening to all of your advice, I decided to take the grill off and check out the MAF again. Well, u guessed it! The MAF is actually functioning properly (thank God) and the Filter was somewhat wet. After leaving the MAF and filter out in the 30 C sun for an hour, they seemed to dry out and after reattaching them, the car works perfect again.
PS: I am really liking my decision to switch from Honda to Nissan!
