1994 GMC K5 4X4 350 engine with 4L60E automatic transmission. I have completed a tune up and the milage is 6 mpg, not any better then before the tune up. I have replaced the following:
plugs, wires, rotor, cap, coil, egr, pvc, oxygen, ECU (Computer), thermostat, radiator, exhaust from manifolds back. Had truck put on dyno and no problems reported, but there is something wrong. Had the electric system checked out at Auto Electric Inc. and no problems found. Black smoke out the tail pipe  when I take off from a stop signifying to much fuel. Gets the same milage highway or town, babying it or stomping it, pulling the boat or not, 60mph or 80mph it doesn't matter 6 mpg. Where is the MAP (Manifold Absolute Pressure)sensor and IAT (Intake Air Temperature)sensor located? If it could be something other then the MAP/IAT sensors I would like to know that too.
