One day I was driving my car and it was running fine, all of a sudden it started to make a sputtering sound on acceleration and a feel of power lose. Its almost like a missing sound. I have a new coil I've put on it and the plug wires are fairly new, I also replaced the spark plugs, but the its still there. When not accelerating you can't hear or feel a diff. only when accelerating or easing off the clutch while giving it gas. Also when I changed my plugs I noticed oil on bottom of the 4 and 8 spark plug.
