I got 28000 miles on the car. The CEL popped up when I was on my way to Canada after like 200 miles of driving with my turboback exhaust. Will the dealer replace the O2 sensor even when they see my full turboback exhaust on?

 

It dosnt need an O2, it needs a cel fix. Check out Vivid Racing, they have one for 30 bucks, and it took me 1/2 an hour to put on.

Yup. the problem is I do have the CEL fix and the CEL was still there. I know the fix worked because before, my A/F gauge was bouncing up and down, after the fix, it just stays stoich. I dunno wat else to do.

 

make sure you have the correct cel fix. the 04's need a differnt one then the o2-03's do.

did you pull the cel code to make sure that it was a p0420?
