my 2003 ford focus makes a loud vibrating noise when it starts

Resolved Question:

my 2003 ford focus makes a loud vibrating noise when it starts up cold. After about 30 minutes of driving it quiets down. The motor mounts appear to be ok and the timing belt was recently changed but the problem persists.
