I installed the tokensolutions plug and play O2 delete for my '03 just this past weekend, today while driving, the CEL turns on and the trac off light starts blinking... I configured the unit correctly for '01-'03 and the green LED inside is blinking when the car is on. I plug in my OBD2 reader and it says both of the cats are below efficiency, P0420 and P0430. What's going on?! I thought this was the end-all solution to the damn cats! I need to get this car to pass emissions this weekend or else I'm facing some hefty fines. I have the original sensors plugged back in for now.
