When was the last tune up? Have you checked the plug wires to verify proper firing order? Have you done a compression test?

firing order and timing is good now the truck is flooding out and i just put new plugs in it

Coolant temperature sensor

Have to agree with jeepmedic

Have you verified the o2 sensor voltages are switching and match the rich condition your experiencing? Can they be made to switch manually?
