Choppy Vehicle Movement

[Danickar]

Ok.  I got my vehicle to move in the directions I was trying to get it to work.  Now, the only problem is, the movement is extremely choppy and "warp" like. 

 

I am sure someone here has experienced this and can point me in the right direction to solving this.
