Overheating and raw gas being pumped into exhaust
I can run my truck for a while and it will overheat. I thought it
was the O2 sensor or the fuel pressure regulator, so I
replaced them both. I seen the exhaust was rusted, had that
replaced. The cylinders may be miss firing, so I'm changing
them. Could this be the reason for over heating and raw fuel
being dumped into the exhaust.
