My car has started a loud rattle...
The rattle goes away while I'm accelerating or going above about 15 mph, but it is AWFUL when I'm stopped or idling. It is worse when I'm turning.
Also, there is a weird click when I press the gas and again when I release it.
I just had my oil changed 3 weeks ago, and my tires rotated. I do have a small coolant leak, but I keep an eye on it, and it isn't an issue. My oil is clean and full, not milky or foamy.

Does anyone know what's wrong!?

Check to see if the noise is coming from a heat shield on the exhaust system. Take a rubber mallot and tap on the exhaust to see if you can duplicate the sound. Let me know what you find.
