My car just started today vibrating really badly at any speed, the faster the worse it is naturally...tryed fooling with the breaks, in gear or not no difference, any ideas?

 

sounds like a dead cylinder

 

When moving or just standing still as well?

 

You don't know whats bad vibrating! My went kaboom yesterday, so have to replace the whole engine now. Anyways, it sound like a cylinder like its already been said. Or if it vibrates and maybe chokes even when idling it maybe IAC.

 

+1
if it is only occurring while the car is driving, its probably something in your driveline, like a shot u-joint or an unbalanced driveshaft

 

Sucks for you!

 

I know man, sux big time! Just when I had my h/c/i done, and didn't even last for a month! Well, it was a fun month at least, lots of fun killing 3-4 GTs, but now back to stock.

 

Or loose lug nuts.

 

it only dose it when moving...plus when easing the clutch out, right as i get moving in 1st n 2nd theres a raddle from the back somewhere...ima check the lugs n plan on getting all my tires balanced by a friend...but it's still vibrating whenever i drive it...and for some reason when accelerating it's not as bad, n it the worst when not touching the gas pedal n just crusin...it even shakes the change in my cup holder

 

It really sounds like a shot u-joint to me. I would take it to a drivetrain or transmission shop and have a technician take it for a test drive, see what their input is.
