A vehicle can hesitate during acceleration provided a fuel injector is not working properly.
Mileage
Yet another way to find clues about the condition of your injectors is by figuring out the mileage that has been traveled with them. Because experts suggest that fuel injectors should be cleaned before reaching 30,000 miles, distances over this benchmark indicate a need to at least have your fuel injectors checked.Symptoms
There are several symptoms an automobile can display that will help you determine if your fuel injector is working properly, such as power loss to the vehicle. A car that hesitates when you attempt to take off from a dead stop is also a classic sign of fuel injector problems.
Testing
Another way to check and see if your fuel injectors are working properly is by running a flow test on them. The standard rate at which fuel should flow from the injectors can be compared with the injector's current flow rate. A flow that is not up to par indicates that your injectors have problems that need addressing.
Properly working fuel injectors allow a vehicle's engine to run and perform at a high level. However, even a slight clogging of an injector is enough to cause driveability issues with your vehicle. It's beneficial to be able to determine if a fuel injector is working properly.
