i have a 2004 1.8t a4 , and suddently start it to vibrate alot every time i press the gas pedal starts to vibrate the whole car, but when increase the speed to 70 and over stops most of the vibration anyone can help me thanks!!![>:]

 

So it's vibrating when you're driving? Cause if you're moving and notice alot of vibration it could a wheel/tire balancing issue. (although if that were it, you would probably still notice it somewhat above 70). If it's vibrating while it sits, but the engine is being reved, I'd check for a mis-fire maybe. When my car mis-fired it vibrated ALOT. You getting any CELs? You try pulling codes? Made any mods lately?

get the codes pulled..probably the coil packs sounds like the same thing that happend to me, i changed the coil packs and problem solved..

 

If u change the Coilpacks, make sure you buy 4 brand new ones. If you just change one, it'll put a different load on the others and cause them to fail.

 

i check the engine mounts and found out they were crack, didn't know that they were filled with oil so i guess i need to replace them and that might resolve the vibrations
