Check engine light 95 S320
 

Hello all, I have got these codes from a 1995 S 320..
035 o2s ctrl sys. Rich Stop/max. too lean.
084 Sh-term self-adapt, idle p. load excd.
po 133 02s circuit slow responce.
This car has 67000 miles on the clock.
I would guess that the o2s is bad.. What do you guys think about this.. I cant find any information on the po 133 code..
Also I just put a new engine wireing harness on and got these codes after a couple of days or running..
Thanks..

Rob..:confused:
