RE: check engine light

it may have a bad cat, which is souring the o2s...

RE: check engine light

I have a 96 es300 with maybe a similar problem. The engine light stays on and im getting poor milage and a raw fuel smell sometimes but no leaks. It also has a rough idle, could this be a bad cat or O2's? they have almost 200k on them... Thanks
