4th Spark plug well wire vibrating...???

[RitdoggyGS]

I just changed my spark plugs yesterday....

All went well, but in the 4th spark plug well... there was a lil bit of oil on the threads/tip of the spark plug.

I cleaned up the well and inserted the new plug, and started the car... it started and runs fine! I have run it for 2 days now.. and there has been no problems or issues!

I open the hood to check again and the spark plug wire on the 4th well is vibrating a little bit.. The other 3 are not at all...

There is no black or blue smoke coming out the tail pipe, no check engine light, or any mis firing/hesitation??

Any ideas to the vibrating of the 4th spark plug wire would be greatly appreciated

Its is plug wire all the way in? It just might not be snapping down onto the valve cover like it should? There really shouldnt be much of a reason that one plug wire vibrates and the others dont....
