To Whom It May Concern:
The ol' "Check Engine Soon" light is on in my beloved 1999 Suburban LS. I have repeatedly cleared and pulled DTC P0430. I am curious as to how I differentiate between a bad downstream O2 sensor and a bad catalytic converter? Amazon has the appropriate ACDelco HO2S; if that's my issue...how hard is it to remove and install one of these? If it's the catalytic converter...where the hell do I begin? Any and all advice and direction is greatly appreciated. Thank you for your time.
