Faulty air mass meter? 740-760 1986

ICQ>

Have a 1986 760 Turbo with 275,000 miles. Yesterday the engine suddenly started running rich. Sluggish uneven acceleration and some visible black smoke. Later in my travels it ran fine. Last segment of about 40 miles was pretty consistent with low power, some black smoke. This AM I pulled the plugs and they were fouled like too much gas. In thirty miles of use today, ran fine, then the same thing happened again. I supect the air mass meter since I had similiar problem at 100,00 miles and after several trips to the dealer, they replaced the air mass meter and the problem was solved. My question is, is there some way to test the air mass meter to see if it is bad? Could it be something else? Any advice will be appreciated.
