So in the end the spark at the plug is both weak and erratic. As they tend to be 'tighter' when cold but as the leads heat up, everything expands and that close gap widens, and the electricity needs to jump a wider gap, this can happen numerous times in a damaged lead. The ignition leads are most likely at fault. If the engine starts OK and runs when cold then starts missing and jerking. Again heat and cold cycles tend to cause the leads to break down over time, usually on the inside where you can't see it. The main causes of misfires are electrical faults within the ignition leads or faulty plug. Oil however won't really affect your car by causing misfires, as all it might do is create a bit of resistance and oil doesn't tend to conduct electricity. As the oil level rises in the well it moves it way up to the cap of the plug. As the ceramic can no longer efficiently dissipate heat. And even if cleaned up should really be replaced. Once your plugs have bathed in oil for awhile, they are pretty much done. Oil like water and electricity always finds the path of least resistance and after some time, creates a big enough gap to allow more oil to flow in to the well. After a number of years the gasket shrinks due to constant heating and coiling cycles and from the contaminants in the oil. Oil in spark plug wells is almost always caused by an old perished gasket. Tighten the spark plug finger-tight until the gasket reaches the cylinder head, then tighten about turn more with a spark plug wrench. Remove the dirt at the gasket seal of the cylinder head. & i really think u helped me solve the mysterious rondevu my g35 is having. Confirm that the thread reach of the spark plug is the right one for your engine. burnt but dry, othr 3 Rside where the oil cap is at, compl. sensor.?Came up 1 at a junkyard, popd that in.

Valve cover gaskets will need to be replaced in addition to the spark plugs, wires or coils.

If your vehicle is equipped with spark plug wires (as opposed to a coil-on-plug system), the wires should be replaced at the same time.Plugs should always be promptly replaced per the manufacturer maintenance schedule even if they appear to be working perfectly.Consider earlier than required inspection and tune-up if you operate the car in severe conditions. High-speed driving may accelerate spark plug wear.When having spark plugs replaced keep in mind:
