Default 1993 lexus es300 mystery problem

Hey how is everyone,
I got a problem with my lexus. The engine sounds weak and won't drive pretty much at all. There's a rich gas smell when it runs. We checked the fuel pump and it operates fine, we cleaned the throttle body and it's fine. Any ideas?

Is your throttle opening? Throttle cable adjusted properly? Plugged up CAT?

Default Mystery problem

Change all 6 spark plugs iridium not any cheap ones. Put slick 50 with new oil change. Feel the difference.
