Engine Performance problem
2002 Ford Taurus 6 cyl Two Wheel Drive Automatic 53000 miles

i have replaced egr valve,plugs and plug wires already. Engine still missing and sluggish with any throttle. Intend to replace fuel filter and EGR pressure sensor , but i need to know its location. I read about your coil pack advice already and it might be next, and where is it located also. Thanks. JA
