First I thought it was wheel or tires so I had 4 new tires put on at discount Tire.
Discount told me they found one bent wheel, & they replaced with the new tires.
Vibration still appears.

So I decided to change ALL engine AND transmission mounts.
Vibration is still there 40-50mph and only 40-50.
Feel slight vibration through the gas pedal when it does vibrate, so that's why I decided to do all the mounts.

Red flag***
The vibration WILL GO AWAY QUICKER WHEN I ACCELERATE QUICKER.
WHEN I ACCELERATE NORMAL IT VIBRATES LONGER
Also
No vibration in turns or braking.

I am pretty seasoned in the automotive field. (Currently working for mobile automotive repair)

I have had a 03 Cavie and it was totaled when a red light runner decided to run into me. And I never had this problem with my 03 Cavie so I am out of ideas. I know there are plenty of ppl with Cavaliers so I hope my vibration isnt just on my 05.
Thanks for any input
-Andrew
