DOHC s13 code 33 and 32

[gordonliu]

i have a 92 240sx. my cel goes on intermittently while driving under certain conditions (engine braking, sometimes under acceleration, and other times).

I checked the ECU codes and i have code 32 and 33. those are egr function and exhaust gas o2 sensor.

im trying to see if anyone else has had issues with these codes or if anyone knows an easy solution to my problem (cel)

i need to get my car smogged soon, and im trying to lick this problem before it becomes too much of an issue
