My car was vibrating and shaking when it was cold and then it would go away when the car got warm. Had it diagnosed and it was the passenger side motor mount and the dog bone needed to be replaced. I purchased after market parts and had the job done professionally. Instantly the car was worse than before with the vibrations and it was loud! I gave it a week to see if it would go away but something strange happened, The car would drive smooth when it is cold and once the engine warmed up the noise and vibrations came back. Also there's loss of power and the car hesitates when I press the gas. I purchased oem parts this time but before I install them I would like feedback if it really is the aftermarket mounts that are causing this problem. The car drives like it's brand new when the engine is cold. Please help. Thank you

Do you have a check engine light on? Possibly something was disconnected when installing the new mount and wasn't plugged back in. I could see vibration from a new mount but loss of power and hesitation would be surprising.

no check engine light, and that's why I'm baffled.

See my post about hesitation issue

My hesitation when pressing gas was due to a crack in this part, intake boot.
