There's oil in my spark plugs and the engine****** while driving sometimes. The idle seems fine its at a 1000 rpm but while driving it will drmatically drop but wont turn off it just******. Theres no wierd noises. It's a 1995 mitishibishi expo 4 cylinders. What can it be and what should I do to fix it.

Oil is getting into the plug holse via the plug seals under the valve cover. This would result in misfiring and erratic idling.
