How many miles on the car??
Standard trans or auto???
There are two trans mounts I believe they are oil filled.
One center motor mount.
If they are bad it could be the cause of the vibration at idle.
The whoosh whoosh that increases with speed sounds like rotating mass that is out of balance.
Pull your front engine cover.
The one behind the seats.
idle the motor and see if anything rotating like alt. air conditioning pump, anything that rotates is out of balance or loose.
Then look at your axle mounting flanges to the transmission.
There are 6 (I think) torks or allen head bolts make sure they are tight.
Let us know how you go
