I started my 94 gt mustang this morning and It started vibrating bad. It vibrated a little less after it warmed up but still way more then normal. No weird noises. Temp in normal. It vibrates really bad at all speeds. What did I break? Thanks in advance for info.

Stop driving that car! Harmonic Balancer.

harmonic balancer or fan most likely. I remember I put one of those metal flex fans on my car and it ran great. Then one day I did some work on the motor and left a few of my wrenches in my tool holder (read: top of radiator), and started the car... the fan hit the tools, sent them flying 30 or so feet, and the fan was bent. From that point on, horrible vibrations so bad i thought the car wouldn't be the same. Swapped back to stock fan, presto. Looked good from then on.
