Yes it will screw up your emissions test because when it fails it generally will cause fuel rich environment. Make sure when your replace the Front AF sensor (O2) you also clean you ICV (on the throttle body) with some carb cleaner and a toothbrush).

I have a 2000 Outback and I am having the clutch judder problem. I had one independent mechanic say he would not do the work because Subaru has not solved the problem and that they keep changing the clutch kits to try and solve the problem. I guess now Subaru recommends as replacement to be a sport clutch and a new flywheel. Anyone had this done? Did it work? How many miles have you driven with the new clutch kit. Any other info? Does anyone know of class action suit against Subaru for this problem or a recall coming down the line? Thanks for all your inputs.
