Overheating and raw gas being pumped into exhaust

Asked by Jul 28, 2017 at 07:46 PM about the 1996 Ford F-150 XLT LB

Question type: General

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.

Raw fuel is probably from a miss fire. I would test compression and the head gasket. Overheating could be failed head gasket/cylinder head/block. If fluids are fouling the plugs it will miss and dump excessive fuel which will ruin the cats.
