I had 1900RPM shaking and noise problem...
And I had never had that probolem till 2 months ago.
And... I found why it started...

Answer was gas...
I read about gas from this forum and changed mine from 93 to 87...
and today i tried 93 again and that shaking was disapeared...
and i feel like i have more torque than when i used 87...

If you have 1900RPM shaking problem, use higher octane gas...
At least for me, it worked

ehhh, maybe your fuel; injectors need to be cleaned, a bottle of injector cleaner may be a good ry
