Why do your spark pulgs spark on the outside of the motor?
If you see sparks coming from your spark plugs something is wrong. You could have broken insulation on the wires. You could have broken spark plugs. You could have too much grease and gunk on the wires. If the spark is outside, it is not burning the gas inside the engine and you are sending unburned gasoline out the tailpipe. Tell me which brand of gasoline you are wasting your money on and I will buy stock in the company. The cure is probably new plugs, wires, etc.

Question that comes to minds here, is did this car start before the plugs were changed? The mere changing of the spark plugs is not the "miracle cure" for all car starting problems. There are other things like the fuel pump, the starter motor, the battery, the fuel lines, the fuel pump, the fuel injectors, the distributor system, gas in the tank, etc.

Absoutely, it may be the culprit of the irregular idle. Start with the simple stuff first: Spark Plugs, then Spark Plug Wires, then Coil Pack, then the IAC Sensor and Throttle Positioning Sensor. If those do not cure issue then it may be fuel related: injectors and/or fuel pump

How do you remove the oil from your spark plugs?
If the oil is found outside of the threaded portion of the spark plug, you probably have an external gasket or seal leak. Replacing the faulty gasket or seal would stop that. If the oil is found on the electrode side of the plug, you probably have worn rings and/or bad valve seals. This condition would probably be the result of a high mileage or poorly maintained engine. Rebuilding or replacment would be necessary to properly cure that.
