I have a 1999 Chevy Blazer that has a loud rattling sound coming from underneath the vehicle when I start it up and when it idles. It seems to make less noise when I am in motion. Any ideas?

Do you
have the same problem?

Possibly the cat broke loose and is rattling. You need to get under it and start smacking things around to try to duplicate the noise. Also possibly a heat shield came loose.
