We've checked, cleaned, and replaced (when needed) everything from the air intake filter, to the Mass Air-flow sensor, to the Oxygen sensor, cleaned the injectors, changed the fuel filter (fuel pump works fine), changed spark plugs and hi-tension wires... but still experience sluggish acceleration from standstill and terrible gas milage. I mean, either give me no power but great milage or bad milage but great power... but no power and poor milage is just terrible. The only thing we have not yet checked is the ECU, which controls the air/fuel mixture and timing of the engine. I can't imagine why these things would "lose" their programming or why these things would ever require any reprogramming to begin with. Any ideas anyone? Did we miss anything in our checklist? Thanks.
