P0420 Code
Installed a Injen CAI and 2.5" ZZP Catless down pipe on my LE5 2.4l over the weekend. I am now getting code P0420 which I assume is from removing the cat. I am planning on getting a tune here in a couple weeks and am assuming I will need to delete the rear o2 sensor. I guess my question is will it cause problems running with that code for a couple weeks until the tune? Or is there another fix for this code?
Thanks,
Matt

Yes it is an annoying little light! Was talking to the tuning shop and apparently they freak out about the CEL's and said they wouldnt touch the car with it on there. I guess just tell them all it needs is a rear o2 sensor delete?
Thanks for the input! I appreciate it!

Clearing the code won't make it go away. The code itself needs to be deleted via HPTuners. Its nothing to be worried about. The only harm it will do is if you get emissions run on your car. It will fail obviously. However I don't think you care about emissions since you went catless lol

spark plug non fouler trick. i had to add a 90 degree elbow to mine in addition to the non fouler trick to prevent the code from returning. you can clear the code simply by unplugging the battery.

Nah I called and was asking about how much a tune would be before I had verified the p0420, told them it was most likely a p0420 and they said they wouldn't touch the car until it was taken care of or checked out further. Which I think would be normal.
