I have a 94 gmc z-71 pickup with a 5.7. Engine runs great when its cold but hesitates and stalls after its warmed up and I give it gas. I have changed plugs, wires, cap, rotor, pcv, fuel filter, check timing. It idles good cold or warm. Any ideas? I got this truck from relatives and it ran much worse when I got it.
have the same problem?
