Re: mass air flow sensor

Removed one spark plug today and it is extremely black on one side and brown on the other side.Another weird thing I noticed was my exhaust getting really hot in a short period of time.Less than a minute.I coulnt touch the front of my catylatic converter but the back of it was just luke warm.Do these become clogged over time?
