Hello. I am in need of some help. I have a 2005 xc90 with 207,000 miles. Recently I changed the upstream and downstream o2 sensors , catalytic converter, torque strut mount and tuned it up. Now at 2500 rpms I have a crazy sound with serious vibration. Again it’s only between 2000-2500 rpm’s and in drive. It only does it in drive. Never in nuetral or park. I have gone through everything that I can think of and can not find anything. It sounds like a major exhaust leak but again all is right.

Additionally I have had misfire codes thrown but that was nothing really new. Any ideas ??

All parts are replaced together? Then it is not easy to isolate the issue. What does it sound like? Sheet metal grinding?

Yes All done at once. Since I’m new to this site I’m not quite sure if I can upload a video or not. But if I can I’ll do so so you can hear it’s very strange
