Check the condition of the spark plug in cylinder number 6, it must be free of oil or any contaminants that prevents it to fire; If there oil or contaminants present, you have a problem for that cylinder. And if the spark plug is good, check the spark plug cables seat in the ignition coils if fitted properly; loose cable will create resistance. If a coil problem is suspected, measure the coil's primary and secondary resistance with an ohmmeter. If either is out of specifications, the coil needs to be replaced. A coil can be easily bench tested with a digital 10 megaohm impedance ohmmeter. Refer to the vehicle manufacturer’s service information for the coil test specifications because the values can vary depending on the application.
