 couldn't find a defective line- at least visually. Before jumping in real deep and
checking all hoses with pressure and a guage, I decided to stick my TAP box
back in and make some runs. 2 days later and no check engine light whatsoever.
I hate to point at IA's box as the culprit but it must be for now. Time will tell and 
thanks to everyone for all the reply's I received.
