My tiburon has a small vibrate when the car is idling. The rpms don't jump or move. Just vibrates. How ever if I give it gas the car begins to vibrate a lot almost shakes. I can't figure it out. Tires are good. I just want it to stop and need to be pointed in the right direction.

The motor mounts may be bad. You can check this by opening the hood and getting a line of site on the engine. With the parking brake on give it a blip of gas and see if the engine moves more than a half inch or so. If you replace motor mounts you must replace all the mounts and the transmission mount all at once or the older mounts will quickly fail and then break the new mount.

Sorry I wasn't clear the first time. :(. When its in idle n I hit the gas it goes away. But when I'm driving and usually when accelerating it vibrates, almost feels like it shakes. If I let off the gas or just stay at a steady speed it stops. Only when I hit the gas is does it.

It could be a combustion issue. Things to look at are the compression and maybe the EGR valve. You might also check the fuel pressure. However I still think the motor mounts are suspect. Below is a link explaining vibrations;

Hey, I changed the mounts and still the same vibrations. For some reason sometimes it's hard to shift into gears. I will have to wait until the rpms drop. I'm so lost lol. I just want to figure it out. Please help
