Okay on this past Sunday I tracked every hose on this and replaced majority of it with new lines/connections.
On the manifold under the throttle body I had two end caps in place and replace the four other lines completely. Even replaced other hoses that where drying out as well. Then Sunday afternoon we reset/cleared the code out once again.
I ran it for just about 1 complete day and the check engine light came back on.
This time I went right after the air box area and double checked that. I put a new air filter in, sprayed some air manifold cleaner down it and this morning I replaced the Mass Air Flow Unit. Then closed everything up.
It still has the code at this point, due to the fact that I did not clear it out yet.

What to do next. I need to resolve this by Friday for the State Inspection.

Thanks.
