I was driving along doing fine when a loud pounding noise came from under the hood. Immediately pulled over & shut off the motor. One of my spark plugs had come out and was "ping-ponging" up and down (dinted the hood). My question is how unusual is this? Do spark plugs come loose? Although its been over a year since my last tune up should this happen? It was reinstalled and everything seems to be running fine. What do I listen/look out for in case more damage was done than I can see?
have the same problem?
