Fuel dumping

I have a 1986 F250 302 EFI and I am having a problem with my injectors, they are dumping more fuel than they are suppose to. Which in turn makes the motor run rough. Has anyone had this problem before. I had a neighbor who works for ford check out the fuel system and everything checks out. Any ideas where the problem could lie?

Map sensor or a cracked vacuum line to it. Check the vacuum signal to the map sensor, with low vacuum, it will run too rich.

I just actually changed the map sensor and it is running a little better, so would a cracked vacuum line going to it cause that?
