So Fix it

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.

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 injectors current flow rate. A flow that is not up to par indicates that your injectors have problems that need addressing.

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.

When one brake light stops working, the most common reason is that the bulb has burned out. Bulbs are inexpensive and easy to replace, though accessing them can be difficult on some vehicles. Some brake light housings must be removed from the outside, while others are accessed behind the trim inside the trunk of the car.

If all of a vehicles brake lights stop working at once, the most likely reason is a blown fuse. The owners manual for the vehicle will direct the car owner to the location of the fuse box. The manual will typically have a diagram of the fuse box (a diagram may also be included on the fuse box cover), allowing the car owner to quickly locate and replace the fuse for the brake lights.

Wiring may break or become loose, causing problems with the brake lights. A visual inspection of the brake wiring may show damaged areas that need repair. The brake lights may also fail if bulb sockets become too worn.
