I noticed this on Sunday... metallic rattle idling in gear. In neutral or park the RPM's go up and it goes away. Give it a little gas and bring the RPM's up to around 800 in gear, and it goes away. The noise isn't noticeable with the windows up and seems to be intermittent even at idle.
My theory is.. the engine bogs down a bit idling in gear and RPM drops to about 600 and the rattle is occurring because of that. RPM's hit 800-850ish.. and it goes away. Idle in neutral is about 800-850 and smooth.
Any ideas? I already checked the exhaust heat shields.. all seemed to be intact.
