So heres the story. I put in a WS y pipe, and my car starts running kinda crappy. I get a knock sensor code and replace the knock sensor. Then i get a o2 sensor code, so i replace that. My car is still idleing wierd and feels odd so i change my spark plugs. I had a leak in my y pipe so i fixed that too. Now i still have two codes and i am very cunfused what they meen and why i have em. I am getting (02 01) and (04 12) Can anyone help me out please.

I need the (04 12) ran as weel as any info as to what the hell i can do because my registration is due on the 2nd and i need to pass smog. BTW the car is still idleing wierd.

Thanks guys/gals,

Look in the ECU stickies for the code definitions.

Just to make sure, that's the one closest to the firewall/passenger compartment (not the radiator side). Did you reset the ECU using the screw method? I had to reset mine after I replaced my rear O2 sensor.

And for the idling, check all your vacumn lines and make sure there are no leaks.
