On my 92 SC 400 after about 2 days the SES light comes on and the TCS goes off, I am getting a code 25 Lean but it smells Very rich. Also I get a 41 sometimes the TPS I have tried to adjust it But don't know which one its the primary and the secondary and the specs etc... Any help would be amazing!

you probably need to replace your o2 sensors if they have over 100k on them. thats the first one.
How many miles do you have and have you ever replaced them.
also 2 days after what? buying the car? washing the engine bay? lol help us out here
your primary tps, is on the opposite side of the throttle body arm which has the main throttle cable stuff on it. this is the main engine throttle blade.
your secondary tps (more towards the passenger side), is opposite this cylinder looking trac control thing coming out the side of the throttle body. this is for the trac control.

Thanks for the reply,the car has 158k miles when I picked it up. As for what's been replaced I do not know lol. I know the car was was serviced at a local Lexus dealer that's about it lol. I was looking at the O2 sensors and they look to be the original ones also where do you unplug them because if I rem ember the wire just goes in to the body ... By 2days I mean I will clear the codes and the see light will come back on in a couple days. With the same 25 lean code and sometimes the 41 also .
