Recently I've been hearing a rattle at low RPM's. I will try to upload a video but I am up to date on all check ups. (105k miles)

Any idea what it could be? I tried searching post but couldn't find anything.

 

Heat sheilds are super common causes for rattles. Sometimes the rings come loose and just rattle around on the pipe and sometimes the welds break and they buzz at certain rpms .

If you can get under the car and hit the pipe with a mallet in different places you will find the problem if it's exhaust related. The weld buzz one is usually near the front.

 

On super cold mornings first drive I have heard some engine noise.

 

Yeah I think this could be it but the rattle stops after 5 mins of driving or going uphill.

 

Does this sound go away after idling or while driving a few minutes?

 

Yeah on very cold mornings it makes some racket til a mile or so.

 

Still cant figure this out It rattles only on slow acceleration (on both short and long drives)
