it just started about a month ago image.
my car rattles when I first start it or it gets cold what could it be? on 2007 Ford Expedition
Tap cat. converter with a rubber hammer to see if it is the problem. If not then try other cmponets where it sounds like it is comming from! May need it on a lift to help find the noise. Possible engine timing componet, let a mechanic listen to it if possible.
