- Yep the only problem is that it has limited inputs. Make sure that that
- techy sets it up to monitor on the fuel flow and injector duration. they can
- then calculate the actual amount of fuel going through each injector. Then
- they will probably confirm injector vapor lock and replace your injectors
- with the longer ones that don't do this. If your dealer does not have this
- STAR tester go to another dealership. They are not serious about fixing
- customer problems. Also make sure they have SBD (service bay diagnostics)
- to properly decode the information and get the appropriate bulletins which
- are stored online for the diagnosis phase.
