Those plugs look like old technology and designed more for long life than performance. I would look up your car on SparkPlugs.com, check your local auto parts store to see how they compare in price, and replace those plugs with Iridium versions. I changed out the plugs in the Lotus with only 15,000 miles and it made quite a difference... the plugs were four years old and had been discontinued.

If the car still isn't running well, check the plug wires, and of course try to see where that oil is coming from!
