I'm trying to figure out what might be rattling. I'm sure it's coming from the engine compartment. It only occurs when cruising (neither accelerating nor decelerating). Higher speeds it doesn't occur for very long (for maybe a second) but under 35ish on level smooth roads I can get it to chatter and it will continue until I give it some gas or lift off the accelerator.

I saw someone else mention in another similar thread to check heat shields, so I'll do that when I can get it back up on a lift. But I'm looking for anything else that might be worth checking while I have it up.

Thanks for any suggestions you might have.
