I have a 97 disco that's throwing misfire#4. I replaced the pulgs and wires had the code reset. The check engine light came back on and it still runs rough above 50 mph. It seems to run fine under hard acceleration past 50 but when cruising with light pedal pressure from 50 to 70 it sputters. I am wondering what else coul be the cause of the misfire other than the plugs or wires? Coil pack? Any suggestions would be appeciated.
