5 ltr. beater

hey guys, i'm a little confused. I have a code 33 on my ECU. the code chart states that it's an o2 sensor for the 300ZX left side, or for all other models, its an EGR malfunction. Obviously my car falls under "all other models", but which one is it? O2 sensor or EGR?

well if you have the 300Zx ecu in it, it'd be a an o2

i believe code 32 and 35 are egr related

i cleaned mine with throttle body cleaner. just unbolt it and spray it down while working the valve back and forth with your fingers
