SERVICE INFORMATION

Frequent short engine starts and stops are necessary during vehicle transport to dealerships. Sometimes this causes cold fouling of spark plugs, resulting in engine misfire.


If this condition is encountered on newly delivered or in-stock new vehicles, cleaning the spark plugs will eliminate the problem; spark plug replacement is not necessary.
