My jeep is throwing a check engine light, we read the codes and they say " Random Missfire". The check engine light will go from solid to flashing and then start to miss. It Idles like shit and as soon as it does two O2 sensors just bugger off. The temperature for the Catalyst Temperature bank is normally around 650, yet when it act up it hits like 1500 degrees Celsius. Watch video here https://www.youtube.com/watch?v=rTyPtZAXsYY


Anyone ever have this happen? Could it be as simple as the O2 sensors needing to be replaced?

Sounds like very lean condition, could be bad fuel or excessive water in fuel. Vacuum leak, pressure regulator. Check fuel pressure, it will tell all.
