[QUOTE="New Nick at JDM, post: 1391885, member: 33540"] Is there an aftermarket downpipe on the truck? A P0430 (and P0420) code is normally caused by excess airflow over the cat. The vehicle is normally comparing the signals between the front and rear o2 sensors in order to determine a cat is installed, functional, and not blown out.
