You probably need ignition work, but here's a test--spray WD40 on the distributor cap and plug wires and see if things improve.
more than likely they need balanced. 65;
You have a serious problem. Have your car looked at before you drive it.
The car shakes because your engin has been cold and you sudenly start the car it will shake
You have a tire out of balance. Have all 4 tires balanced and rotated. If it still shakes have the motor mounts inspected.
When the car shakes n it on the correct its becsuse its out of timeing
The engine mount (which are made of rubber) are worn out.
it sounds like your timing may be off
If it only happens when you accelerate the most likely cause is an axle.
You may have a broken engine or transmission mount.
It could be that one of your brake discs is is bent this happend to my Ford Telstar which is just a rebadged 626, if the shaking is more orientated to a corner of the car that's your problem, if the whole car shakes I have no clue sorry
Warped brake rotors/drums.
Sounds like a motor mount or a transmission problem.......
