Question: My car has a pretty serious rattle... what is wrong!?

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!?

If it is coming from the engine itself, it could be noisy lifters or possibly the timing chain.

It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
