Hello there, many faults will cause your 1988 Ford Contour to have a misfire even after the spark plugs were replaced. When oil is seen on the spark plug this indicates that the valve cover is leaking onto the plugs. When this happens it fouls the plugs and can cause a misfire. Until the oil leak is addressed the spark plugs will continue to become fouled. If the misfire persists there are many potential causes such as the plug wires, fuel pump, vacuum leak, oxygen sensor, MAF sensor, or the cap & rotor. A qualified Technician such as one from YourMechanic will be able to diagnose your misfire fault and make any repairs required to resolve the issue.
