Hey guys/girls....
Have a concern about engine shake I have on my 07 TL-S...
idling (cold/hot) no engine shakes... driving on the highway speed of 60mph revs are about 1800-1900 as soon as I accelerate a little i get this engine vibration sort of a like a shake through the rpms till about 2500-2800 rpms..
what could it possibly be? all engine mounts are in good condition, I actually just replace my driver side engine mount..
my understanding if it was a engine mount of bad coil on any spark plug it would shake at any rpm range.. any input will be appreciated. thanks!

 

maybe try down shifting before you accelerate?

 

could be the tranny mounts. im getting similar problems
