Carbon build up?

definately fill up on your oil and coolant.  Take her out onto the highway, or a low traffic road that you can put it into 2nd and step on it for at the least 1/4 mile.  Then run normal for a mile or so..and do it again.  Turn it around and bring her home.  Maybe doing 1 more WOT test.  This will help get rid of the carbon build up, which is very common in northstar engines. 
 
But with it only having 50% oil like you said...that could be it.  When I had my 97 ranger, with 120K + miles on it..If I need to add 1qrt I would get a mild knock at startup when cold.
 
Maybe just do a complete oil change for that matter...if its only at 50%.  You could get a better visable on the condition of the oil.
