It jitters and vibrates even harder when I accelerate "normally" to maintain speed or go faster when I'm at 55 and over.Sometimes when I stop accelerating it'll be smooth. By the way I am not "putting the pedal to the metal" when accelerating. Whats the cause of this, I know I should take it for service but I want to know if I can fix this on my own before I drop a pretty penny on service. Also too driving normally, it seems to pull right all the time. Help please!
 
Sounds like the tie rods to the steering are worn. Because the car is fwd, it would be easier to feel them while accelerating. When power is applied, what is called torque steer pulls on one wheel & not the other. Because the bushings are bad, it feels loose. When the car is at hwy speeds, the imperfections in the road push the front end back n' forth. You'll feel the tie rods going left n' right. The wheels are no longer staying straight n' tight. The alignment is always a possibility, but you need a friend to check this with you. Turn the car off, you get under the front, have friend try to move the steering wheel left & right. Look at the steering linkage, it should move ever so slightly. But the tie rods ends would move even more. You might even be able to hear the metal hitting. Just a suggestion.
