My 91' SC idles alittle rough. I unpluged the mafs and it idled like a dream. Does this mean my mafs is going bad? Thanks

Maybe its just dirty, do you have a K&N with to much oil on it? I'd just carefully take the eletronic sensor off and spray the wires with carb cleaner and carefully put it back.
Good luck
