1990 Corvette ....is There A Way To Test Fuel Injectors Individually?

There are two ways to do this, one unhook the injector wire one at a time or take it to someone who has a scan tool, and have them do a cylinder drop test where they can shut one cylinder down at a time.

All you have to do is go to any auto store like pep boys and ask them to do a scan with your cars plug in under the drivers dash and it will scan the motor and tell you what injector is not spraying and the auto parts store will do this FREE
