i have a 1993 gmc serria 1500 4.3 liter v-6. i have changed the fuel pump, injectors, fuel pressure regulator, fuel filter, cap and rotor, spark plugs and wires. the truck bogs down spits sputters if i get on the gas real hard but at idle it runs great. what else can it be.
am dealing with the same thing, I'll message here when I sort it out, darn thing argued with me all the way to work tonight, had to bump start it in 2nd twice at stop signs.
