To Fordfedup,
There could be several possible reasons for the problem with your vehicle.
Instead of having to play 20 questions it would be most helpful for someone to assist you if you listed what was done, what was replaced,when, and any other info you might have so hopefully those items / procedures can be placed aside. Can we do that?

Thanks again Hanky. So i finally got back to checking this issue out. Sure enough i didn't get the PCV hose connected again to the intake. Problem 1 fixed. So i drove it and it threw the cylinder 5 P0305 again. Swapped 5 and 6 wires on the plug and at the coil pack, cleared code and drove....again a P0305.

So what next? Cylinder 5 Plug? Should i be brave enough to pull that plug if i have a socket for it? ive heard they break easy and leads to more problems replacing them.

What you may have heard about spark plug problems does not apply to your vehicle, so go for it! If you do not have a new plug and have it set to the correct gap , just switch it with another cylinder and see if the misfire moves to the new cyl. When you get this straightened out , your diploma will be in the mail !!!

Just make sure you have the socket on the plugs straight, when taking out and when putting back in.

The socket I would suggest is made by SK tools The # is 4421. It is a 5/8 deep socket, 3/8 drive made specially for working on spark plugs. This tool can make spark plug removal and installation much easier. The length is 3 7/8 in long with a knurled end for easy gripping.

is wd40 ok to use as "penetrating oil" to hopefully loosen the plug some before i try to remove it?

You can use a little WD 40.
If possible , use something like a turkey baster to blow the grit out of the spark plug ports then a quick shot of WD 40. It should not be necessary to use any penetrating oil.
The first plug is the hardest because after that you know what to expect. Take your time and carefully twist the spark plug boots to loosen them from the plugs , then carefully pull the boot off. If you start with the ones up front ,which are easier because you can see what you're doing. If you feel you are over your head when the front plugs are done , don't be shy having someone else do the other three. Spark plugs don't usually come set to the correct gap and it may be necessary to purchase a gapping tool. This sounds like a lot of work, but only takes a few minutes to do.
You might check on U Tube , there are several films explaining the procedure and a picture is worth a thousand words.

Pulled #5 plug and it was in pretty bad shape. It ended up being the culprit i believe. Thanks to all for the help here.
