My mom has a 94 ex 4 cyl . It runs fine but when the car is cruising at a steady speed (35-40) with the gas down just enough to maintain speed, it shakes. cant feel it in the steering wheel or brake pedal.but its pretty bad.

Im just worried about the harmonic balancer. are there any probs with this coming loose and shaking. This started the day it had front brakes and a T belt put on.

 

Did you do your own T-belt? I did mine and had it a tooth off, really messed me up for about 8 hours.. Get your wheels balanced and/or rotated. Also how are your cv-joints? Had a bad one on a Toyota Camry and it drove me nuts, Mainly for the fact that it didn't make any noise when I turned the wheel.

Good Luck, Vibrations suck.

it may be simple but check your fuel filter, or pump...

 

one thing i forgot to mention, it doesnt do it all the time. just mabye 1-2 times a day. I does feel suspenion related. my uncle put on the Tbelt. mabye jacking the car up put some stress on the CV joint or tie rod that were already worn? thanks guys.
