Fuel Injector Replacement
What is a fuel injector?
Fuel injectors regulate the amount of pressurized fuel used for each engine cycle. There is one injector per cylinder in an engine.
How does the fuel injector work?
Each time an intake stroke occurs in the engine, the vehicle's computer will send a signal to the fuel injectors, requesting they spray fuel. For heavy acceleration, the duration of the fuel spraying will be longer than if the engine were idling.
Failing fuel injectors can cause engine misfiring and hesitation. The Check Engine Light may come on and set diagnostic trouble code(s).
What are the symptoms related to a bad fuel injector?
When a fuel injector fails or clogs, engine power is reduced and misfires will occur. The check engine light will turn on and, as the issue progresses, the engine may stall immediately after starting, fail to start, hesitate under throttle or vibrate roughly.
Can I drive with a fuel injector problem?
It's not smart to drive a vehicle with a fuel injector problem. These issues can cause the car to stall every few moments and accelerate unpredictably, creating a hazard.
If the problem is bad enough, the vehicle may not even start, making it impossible to drive.
How often do fuel injectors need to be replaced?
On average, fuel injectors tend to fail after 80,000 miles, and require little maintenance. To prolong the life of the fuel injectors, follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors.
