its a PZEV and has a lifetime filter. i removed it and installed a cone filter but recently had to put it back in so ford would warranty the clogged mani/cat it had last week.. and i do the fuel filter every 15k or so miles sometimes more often, and i had a buddy help me 2 summers ago instal e3's what a HUGE mistake that was.. 56 miles from town had the number 2 plug back completely out just so happened to be one of the 2 plugs my buddy installed.. all bad not knowing at that time i drove it on 3 cylinders all the way to my local ford dealer 1200 later got it back fine they said nothing was damaged so about 30k ago it got brand new oem plugs the ford installed haven't changed them since,I've heard a tune gets rid of the rough idle but its alot worse then it has ever been?

Have you cleaned out your throttle body? I switched out my plugs at 50,000 miles w/ Denso's iriduim ones.

I forgot to mention that. When the car was acting CRAZY due to the clogged cat, before i knew it was the cat when i re installed the stock pos lifetime filter i cleaned maf and throttle body i try to do that every other oil change, i did notice some oil in the bottom of the I/M though, is there a way i can remove the line coming from the back of the valve cover(oil breather) i think and just run a hose down with a filter on the end? i think that is where the oil is coming from, if im not mistaken oil in the intake is not good??

Sounds like PCV replacement time, its under the intake manifold and a pain to replace.

The orange neck the hose is attached to going into the seperator is the valve.
It sits in that plastic case on the block.
