PO430 Code 2005 F150
I have a 2005 f150 5.4 3v newly install factory reconditioned engine. I keep getting a PO430 code every 70-100 miles. Not sure how exactly to check and eliminate O2 sensor from being the problem.

05 5.4l 3v s.crew lariat
New engine --old exhaust -old o2 sensors
Have a good exhaust shop check on cats . But me I would first replace all 4 02 sensors as they age and go bad . I have new ones waiting to go in myself , no symptoms yet ..
