any one know how i can get rid off the 02 sensor malfuntion check engine light, and also a car won't start code, but it start just fine thanks in advance.

Maybe an auto parts store has a code reader you can borrow to clear the codes? Chances are that 02 sensor malfunction CEL will come back. Do you have an accessport or any other engine tuning? Are you running a catless downpipe?

yeah i have a catless downpipe. yeah i clear it with my code reader but it came back on is there any way i can rid rid of it with a accessport. thinking of buying one oh yeah no engine tuning.

If you get an access port it will prevent that code from popping up. The problem is you are now catless and your sensor is detecting that. So technically nothing is wrong with your car but the sensor is out of whack because of of no cat's. Cobb fixes this with their accessport, or I know back when I had my 02 wrx you could get a resistor to put in the plug where the sensor wire plugs into in the engine bay. That would be the cheaper fix. Just do a search here or on nasioc for 02 sensor resistor or something like that.
