Monitoring misfire current counters, or misfire graph, may help isolate fuel injector causing condition. Operating vehicle over a wide temperature range may help isolate fuel injector causing condition. Perform fuel injector coil test within conditions of customers concern. A fuel injector condition may only be apparent at a certain temperature, or under certain conditions. If fuel injector coil test does not isolate condition, perform fuel injector balance test.
