Can you post the exact codes? Like Pxxxx where the x's are numbers or post the numeric codes. You don't want to replace anything you don't need to.

It's 45, 61, and 67.

Clear the codes and see what comes back

So I cleared the codes at work. I drove the car home which is about a 15 min rides and it didn't throw any codes. Now the car idols fine at 800 or 1000 rpms. I'm really confused on whts going on. Wht should I do now?

So on my way home today the cel light comes on I checked the code it was throwing and it's 67 the cat converter. There do I go from here any body know? Do I need to get cat or something else ?
