I own a 1994 SL2 Saturn. Whenever i Come to a stop, or start accelerating from a stop it sounds like a rattling noise from under the car. Its not really loud, but just enought to hear it. I've put higher grade gas in... I've done regular maintaiace for it like coolant flush, oil, getting tires, etc. But im not sure what would make this noise. Sounds like something is loose?

Dude; check your universal joints. If it makes noise while the car is totally stopped it is not your universals but if they make noise when you let off the accelerator or step on the acceleratori It's most likely the universals,
good luck.

Most likely a heat shield on the Catalytic Converter has broken a weld.
If you do your own work, crawl under the car (while it is on STANDS, not a jack) and tap the catalytic converter with the palm of your hand rather forcefully. If it rattles, yo have sound your noise. You can use a coat hanger as heavy tie-wire to secure it well enough to not rattle.
It is also possible that one of the motor mounts has deteriorated enough for the engine to settle enough for the exhaust to be in contact with the frame.
Some things to check
Good Luck and Merry Christmas

There is a tinnish shield around the cat. converter, they will either rust, or the weld break, and they will make a very annoying rattling sound. A good way to check it, is with the car off, reach under there and hit the exhaust with the palm of your hand or something like that.

I've owned a '97 Saturn that did the same thing. The heat shield over the exhaust pipe broke loose from the rivets holding it to the body. I used zip ties to hold the shield up after that. Not pretty but it works.

No. this is probably some thing like passlock. Pull the constructive cable out of your battery and go away it off for quarter-hour or so and that is going to stop the issue. otherwise, not truly confident. i do not comprehend if this is even legal for a finance employer/lot to positioned a miles off immobilizer in a vehicle probably not.

Sounds like it could be a loose baffle plate in the exhaust system, have your mufflers checked and / or replaced

my '98 Cavalier does the EXACT same thing... my dad says it's just the anti-lock breaks, but i don't think he understood what i was saying because it just can't be that. it does it even if i'm not breaking hard... sorry i'm not much help though =/
