[QUOTE="Skeltor, post: 10834070, member: 42845"] Mode 6 shows misfire per cylinder in percentage. Mode 9 shows any alterations made to the PCM's programming. You must have the proper tool to access this info which most all Ford dealers do. You can have an intermittent missfire that isn't setting a code and mode 6 will show you which cylinder is higher in percentage and that usually means that cylinder is your problem. Then you can test that cylinder/coil/injector and not just guess. Very useful and keeps you from throwing parts at an intermittent problem. [/QUOTE]
