Hello everyone I am new to this forum so any feedback would be really appreciated. I have an 05 Durango V8 that ran out off gas the other day. After I added gas to the tank the car didn't start up right away of course... but soon as it did it started making a knocking/clicking sound from under the hood for about a couple of seconds then it went away. Now it has been making that sound on start up ever since. Any ideas?
