I just started noticing that my Jeep shakes/vibrates more when first starting. There's no delay on start, just more shaky. And I can hear the engine making more of a louder sound. While I'm driving it does the same thing.

 

What? sorry but can you come up with a better description so that we can maybe help you. I just dont know what your trying to say... Does the engine run rough? Have you done any tune-up type stuff, like cap, rotor, plugs, wires, filters ????
