I have a 91 K1500 with a 5.7. I just recently replaced the head gaskets on my truck and now it runs rough at low speeds. It runs fine at idle but when you put into gear it starts to sputter and the lose power and tries to die. it does the same thing while stopping. I have replaced the distributor, cap, rotor, plugs, wires, idle air control valve, EGR valve solenoid, and the coolant temperature control sensor. is there something I'm missing? I really don't feel like replacing every sensor and electronic device on this truck.
