Engine Performance problem
2003 Ford Taurus 6 cyl Front Wheel Drive Automatic 120000 miles

my engine is beginning to run badly as the car warms up and gets worse as the day gets hotter. it sounds like its running out of fuel. i am wondering where, if there is one, the crank sensor is, and the throttle positioner sensors are. i changed spark plugs and wires, and replaced cat. converter
