I need help/suggestions for my 2000 Ford Expedition. Recently, the following were replaced: long block, intake manifold, spark plugs, spark plug boots, fuel pump, alternator, heater hoses, coolant hoses, replaced 2 core radiator with 4 core radiator, thermostat and water pump. After that work was done the valves carboned up heavy and the vehicle was over-fueling. There was no power. The valves were cleaned and the injectors were cleaned and an attempt was made to program the computer (not sure if that was successful or not). Now when the vehicle is cold I get 21 mpg and it has more power. As soon as it warms up, the mpg goes down to about 7 and again there is no power. The temp runs at about 210. Also, a few years ago I put in a K&N cold air intake system. Any thoughts/suggestions?? Thank you.
