P-0420 is a common catalyst efficiency code... logic in PCM has determined the catalyst to be lacking efficiency based on inputs from pre and post cat ox sensors..

8yr/80 part... 10yr/100 to original owner if manifold has crack... VO4 recall for certain yr for cracked manifold.. doubt VO4, as service dept is supposed to run all VIN as they appear at dealer for recalls when in for service...
