I have a 2003 2.5 X-Type with 165K miles. It bucks and kicks when accelerating. The codes say miss fires in 4 cylinders. I'm in the process of changing the spark plugs and found three plugs covered in oil. I also broke the bolt that holds down one of the coils to the plug. If anyone has any advise I'd really appreciate it - thank you

 

I moved your thread here to the X Type Section for better exposure.

 

Thank you
