The truck is 91 ford F-150, 302, 4x4 manual. Bought the truck in rough shape. It idled and ran very badly, so replaced plugs, wires, cap, rotor, and fuel filter. Truck still wouldnt idle well, so replaced idle control module/ motor. When I push in clutch, engine will over rev, or drop rpms to near death levels still. Also, engine misses, fairly bad. In addition, chewing through fuel at alarming rate, about 6 mi per gal on rear, and far worse on front tank I think. No leak in line, good pressure at regulator. Confused as to what would cause the miss and poor fuel milage. Very obvious engine running VERY rich. Any suggestion?
