How do I know my 2002 F250 5.4 V8 is misfiring?

A misfire is very distinctive feeling. It feels like the engine is skipping, or hiccuping. Others may describe it as "chugging along" or "sputtering". This is usually accompanied by a check engine light, but the Ford system doesn't always turn on the check engine light if it is an occasional misfire. There actually is a way to find these phantom misfires as the vehicle computer still records them. You can do this using an OBDII scanner with Mode6 capability.Check out our how-to section for more information on this. The auto industry generally recommends to replace all of the ignition coils because they usually wear in the same environment, and at the same time, so they will normally fail not far apart from each other. Some say that when one coil fails, the others have to "work harder". This is simply not true. They fail close to each other mainly because they are the same age and have the same lifespan. The lifespan of the coils is not known because it varies greatly due to regional climate. Those who own F250s is humid climates are much more likely to experience a failed ignition coil sooner than someone in a dry climate. We've heard of people with 300,000 miles on the original coils, and we've heard of people that have had an original coil go bad with less than 10,000 miles on the vehicle (practically still new).
