Diagnostic Aids

Monitoring misfire current counters, or misfire graph, 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. See FUEL INJECTOR BALANCE TEST WITH SPECIAL TOOL  or FUEL INJECTOR BALANCE TEST WITH TECH 2 

Operating vehicle over a wide temperature range may help isolate fuel injector causing condition.
