Something aint right..
 

I got a '96 v6 mustang and its got over 103,000 miles on it, I dont know exactly how many miles are on it because the odometer is frozen, but anyway, the car starts to shake once I get to 60mph, but once Im about 70 mph the shaking is still there but its not as bad if Im in cruise control, or if Im giving the car throttle, but when I let off the throttle the car starts to shake again.

WTF could that be?

Now Ive heard it could be because the car needs an alignment (which it does.)

And I was wondering if it could be that I need new brakes?

Someone help me out here, Im only just braking into all this automechanics stuff.

problem
 

If your not mashing the brakes when it does this, then it is not your brakes. Unless they are not releasing. More than likley could be align. or could be bad tires. However, I had a 95 v6 and the cam shaft sensor lost its ground and It would miss at different rpm's.

it actually does shake when I brake....unintentional rhyme.

But yeah a bolt fell out of the brakes or some shit like that, then got it fixed, and it didnt shake...now it does.

If I had the money Id go get all this shit looked at.
