Yes, oil on spark plugs can cause misfire. When oil coats the spark plug, it prevents the spark from igniting the fuel-air mixture properly, leading to engine misfires. To fix this, check for potential causes such as a leaking valve cover gasket or worn piston rings, and replace or clean the affected spark plugs. Regular maintenance is crucial to preventing such issues.
