any advice

I was wondering if a cracked piston could be the cause of my earlier problem. (car shaking and smelling) Could any please help me.

A cracked piston would usually cause a severe loss of power, not sure about shaking.

check for water in the fuel lines, check ignition coil pack. What octain gas do you run, could be bad gas. sounds crazy but i had same problem with my 99 purged fuel system and changed gas station and it never happened again

need more details, you need to isolate the shaking.

1. when does it happen ( driving? parked? at what speed? idle? full throttle?, in a turn? etc.. )
2. where does it happen ( the entire car? the front? the back? just the engine? etc... )
3. when did it start ( after you hit a bump, hole? etc.. )

most commonly, a front shake ( violent ) during high idle or driving can be motor mounts, but internal motor damage can cause this to, but you will have a decrease in functionality or even complete lose of functionality.

a shimmy ( liquid type shake ) can be caused by something major/minor internal to the engine, fuel, oil, misfiring, plugs, a/c, etc.

if its something that doesnt show itself off hand, take it to a trusted greasemonkey.
