i just installed a set of ford racing 9mm plug wires a couple of months ago and just noticed today that cylinder #7 is arcing out on the dipstick tube...what would cause this and how can i fix it?? any help would be appreciated

 

Do you have any pictures?

 

take the plug out and see if it is cracked.

 

new plugs...., yea make sure that you didnt bend it enough to rip a lil...

 

Electricity takes the path of least resistence.
