PSD going crazy, need advice!

Hi guys, my Excursion has lost her mind. A couple of months ago, I noticed a slight oil leak from underneath. Didn't think much of it at first because it was small. Small became a lot! It only leaks when cold, when engine warms leak stops. I changed the oil and cleaned underneath to see if it comes back...it did. Now, she starts but idles rough. I can here her missing on about 3 cylinders at idle and at a stop light. When I accelerate (most times, but not all), it accelerates like jolting or lurching forward hard, even at a steady speed. Now she frequently cuts off on me when idling or at a light. Still has oil leak and I'm trying to trouble shoot this before taking it in to the dealer. Truck info in sig! Thanks for the help again guys.

James

I guess everything isn't in there.
Mods are Bully Dog Power Pup set on "economy/tow", and K&N Cold air filter (I know, I'm swithing back to the stock intake, just need to find a minder for my assembly).

ICP sensor is a likely candidate. Look it over and see if that might not be the source. The sensor and harness need replacing if it is the source.
