Epc and check engine lights are on. First time I checked the codes it read two codes. Both are o2 sensors. After 2 weeks the car sounded like it was misfiring and was running very slow( when pressing the gas peddle to the floor it would accelerate almost the same as gradually pressing gas. I n checked the codes again and it had a lot! Misfires in four of the six cylinders. So I changed the wires and coil pack. After doing this the car seemed tobe running better. I took it for a test drive and the car still seemed very sluggish but did sound good. After a mile the car lost all power nd started running very rough
