shaking get it home and when I put it in park it
seems like it wants to turn off but it doesn't.. HELP

Check for a broken valve spring or rocker arm on the number 5 cylinder. Also the #5 fuel injector could be bad.
On a mis fire, if you've changed the coil and plugs, and you still have it, it's not good. Do a compression check. I suspect low compression on the coded cylinder. What happens is the valve seats and guides get worn, or don't seat right due carbon causing low compression. When that cylinder fires, it doesn't fire as hard and as fast. A milli second slower. The computer picks it up and you'll get that code. In the old days the guides were made of bronze, now they are aluminum.
