sc400lver

hey guys, i too have a problem with my 95 sc400. it smells of fuel and runs rough. cat convertors were plugged so we cleaned the 2 up front out and cut out the 1 in back. its better but still doesnt run right. the power steering fluid res was also empty. put new plugs in also. this problem just started one day, no warning. it doesnt run bad if you hold your foot still and dont move it. need your help please!!!!
