Cats below threshold... Well got the old SES light the other day and I took it to the auto parts store and they showed me that was the code. They cleared it and 4 days later the light came back on, Altho I did search all I found that they have drivability issues when this problem comes about. But I dont have that, the car drives fine. I was going to get the catback done in a week or two but now im wondering if I should gut the cat to elminate drivability issues in the futrue and save for headers back. The car only has 54k on the clock so to have cat problems is beyond me.

I just got a code p0420, driverside below threshold. I'm gonna swap the rear 02's one side to the another and then see if the codes changes to the passenger. If it doesn't then time for a new driverside cat. There warranteed for 10yrs 120 miles for 00-02's. Since I live in Ca forget about cutting them.
