hey my 1ggte supra is missfiring from the second piston closest to the cabin, there is a bit of oil on the bottom of the spark plug and all the rest of the plugs are dry. i also noticed a hole on the dissy cap today not sure if that is doing anything.

The oil in the bottom of the plug well will cause a misfire. try replaceing all of the valve cover gaskets and seals.Might at minimum want to replace the misfiring plug as well
