1997 Acura Integra mileage: 150,000. My car started stuttering while on the freeway. When I got home I checked the sparkplugs and two had oil (not burned but liquid). Why is that? Is it the head gasket? It really cuts into the performance of the engine. Is this something that I can fix by following the manual? Pls, any suggestions would be greatly appreciated.
The spark plugs may be fouling because your engine is starting to use oil. This is normally caused by the piston rings wearing. Replacing the head gasket will not cure this problem. As a temporary fix, try running a hotter heat range spark plug to keep the oil cleaned off.
