Sc400 running rough and stinks

Car was running fine yesterday and when i went to start it this morning it idled very rough. When i rev it the rpm's drop and the exhaust sounds different. It also has a smelly odor. Any idea what this could be?

Try unplugging the drivers side ignition coil. If no change on the way the car runs, replace the coil.

SEAFOAM first. Very simple, one person job. Could be a dirty injector or throttle body.
