Need Help!!! P0430 code on 08 1500 SXT 4.7
P0430 code set 3 months ago, reset ECM and now code is consistently reappearing. I have seen threads on this, but involved some modification with headers and exhaust replacement. Every thing I have is stock. 101,000 miles current. Light originally triggered around 85,000. Will replacing down stream O2 sensor cure?
