rattling noise

[4.6powa]

ok, driving my car at low speeds i can hear a`rattling sound. its fairly faint, i can hear it if i am driving close to a building with my window down. it sounds similar to the rattling on start up. any ideas? by the way i am running mobil 1 clean 7500 synthetic and a motorcraft filter.. 150,000 miles, 1995.

thanks.

im running 93. its coming from the engine. thats why i said it sounded like dry startup, and said my oil brand.

Have you had any exhaust work done, I had a weld come loose and that allowed the pipes to rattle where they joined...
