I was driving down the road and my 2002 Disco started running rough. I stopped at the parts store and plugged it in to a scanner. It came up with the code P0300. I was told this is a misfire code. Is that right? I took a look at the wires and could not even see how to unplug them from thecoil pack.

 

Here's the link. The codes and descriptions. Land rover trouble codes

 

Thanks
