If it was misfiring it's probably the case. Fouled plug from not firing correctly due to bad wire(s). I always change plugs and wires as a set.

 

Ok thanks for the help. Ill be back later once i do the plugs and let you guys no whats up with it.

 

Wires and Plugs are fine but its still acting up. You guys think i should go buy some fresh motorcraft wires instead of the onesi tried from autozone? I think they we ultra lights and we checked for spark in each cylinder and tested the fuel injectors and it all checked out.. What else should i check?

 

check for a vacuum leak. spray some fuel injection cleaner around your upper plenum/ throttle body. if it clears up you know you have a vacuum leak.
