95 SL2 Metalic Vibrating Noise

at about 1200-1900 RPM's it sounds like comething is rattling loose. I had
my cat replaced about a month ago so I know thats good.
No Codes.

Any Ideas ?

Possible worn upper engine mount?

 

If you can get under the car(safely) I would take a small hammer and
quickly tap all the bolts of the exhaust system. Listen for a 'thud'
to indiciate a loose bolt, also check for missing exhaust mounts.

My '95 sl2 did that for a long time, turned out to be the cat. Just because
you had yours replaced recently doesn't mean that isn't the problem. Put it
up on four solid jackstands and leave the garage door open for air. Slide
around underneath on your creeper while its running and listen with a
screwdriver in (close to) your ear. You may need to get someone to hold it
at the rpm range where its the loudest.

Obviously this is not the safest thing in the world to do, so all standard
disclaimers apply YMMV

 

I'd guess a worn engine mount.

Is the world vibrating in your rearview mirror?

Not hard to fix.

Probably $100 for the part.
