Trouble with 1988 5.0 GT, Gas and Oil

Ive been having some issues with my 1988 GT, it seems that the car is idling rough, it leaves black spots out of the exhaust and the oil smells like gas is mixed in it. Any suggestions?

Sounds like it's running very rich. With the oil smelling of fuel could be an injector problem. I would be careful running that car if there is fuel in the oil, it could cause much larger problems.

Yep. Could be an injector problem, pull off each wire on the injectors and measure the resistances. Should be about 14ohms. If you have a fuel pressure gauge, check that first, make sure it's not 50lbs or something stupid.
