Seems like my Jeep has some vibrations and has a minor smell of gasoline in the cab once in a while. Anyone know why?

 

well, did you check out the basics first? like tires balanced, or warped rotors? if not i would check out all the easy stuff like that first. idk about the gas smell

 

Check the injectors for leaks (look for wet injector body's) also the O rings to the pressure regulator do tend to fail.

As for the vibrations when,where and how is it happening? lots a possibilities but more info is needed.

 

The vibrations seem to be coming from the motor, when its in park.. Vibrations aren't really an issue. Just the smell.

 

The injectors or fuel regulator is most likely the cause or your smells. Have a qualified mechanic take a look.
