How does a bad injector affect fuel consumption?
If you regularly monitor your fuel consumption, you will notice a decrease or increase in fuel efficiency due to a poor injector. A faulty injector delivers either too much or too few amounts of fuel to the engine than required and reduces the vehicle’s fuel consumption.
Can a cracked fuel injector cause a fire?
Fuel injectors are often made of plastic and can crack, which cause an external leak on the fuel injector. If you notice a fuel leak in your engine bay, you should replace it imminently because otherwise, it may cause an engine fire.
What are fuel injectors used for in cars?
So, fuel injectors are now used in pretty much all passenger vehicles. Fuel injectors are a vital part of a complex, fuel management system. Furthermore, new technology has made fuel injectors more precise than ever, in dispensing fuel. If the fuel injectors are not operating properly, then other parts of the engine will be affected as well.
How can I increase the life of my fuel injectors?
Driving a car hard, combined with short start stop journeys, will increase the wear and tear on injectors. Letting the engine cool down, before shutting it off, will increase the lifespan of the injectors. This will also, benefit the rest of the engine too.
Can you run bigger fuel injectors on a stock car?
You can;t do a stock tune unless you can fool the ecu into thinking it is getting more or less air. If you throw in bigger injectors it will hold that injector open for the same amount of time as the smaller injectors and it will dump TONS of fuel in.
What happens when you install bigger injectors?
Bigger injectors will deliver more fuel, but in petrol engines this means more air is needed to keep the mixture at the best combustion ratio. So if you turbo charge, or supercharge, the bigger injectors will give more power. Otherwise they will decrease power and waste fuel, like running constantly on the choke.
Do bigger fuel injectors make a difference?
Larger throttle body and injectors A larger high-performance throttle body will deliver more horsepower. Depending on what type of engine you have, you can gain as much as 10-20 more horsepower and comparable torque. There is a catch, however. Go too large and you can lose power.
Can I run bigger injectors without a tune?
In general, injectors need a tune. Otherwise, your ECU is trying to drive the new, bigger injectors using the duty cycle and dead times for the old, smaller injectors, which means too much gas potentially at the wrong time (i.e. - running rich and potentially missing).
Do fuel injectors give HP?
The technical answer is yes; fuel injectors can add 10 extra horsepower at peak. However, for some car owners, that minimal difference does not offset the increased cost and complexity of switching to fuel injectors or upgrading the existing stock fuel injectors.
What will happen if I put smaller injectors in my car?
If you change to a smaller size injector then the injector will need to "open" more to deliver the fuel required to achieve any given RPM. Since the throttle control at the steering station is just an "RPM request" to the governor, you would put in the same position as you always did for a given RPM.
Is it worth upgrading injectors?
In reality, if your car is modified to the point at which you need upgraded fuel injectors, you realistically need an upgraded fuel delivery system for optimum results. If done right, an upgraded fuel system will create an atmosphere where the engine can make more power, reliably and efficiently.
Are all injectors compatible?
If the body of your car's injectors is gray, keep in mind: injectors of all releases ARE compatible! So, your car can have injectors with a different release for each cylinder!

How does driving a car hard affect fuel injection?

Letting the engine cool down, before shutting it off, will increase the lifespan of the injectors. This will also, benefit the rest of the engine too. As a result, a well kept fuel injection system, will keep your car going for years.
What happens if fuel injectors are not working properly?

Why is my injector leaking?
Leaking Externally Or Internally. So, the most common cause of leaky injectors is; the failure of the O-ring, where the injector meets the fuel rail. The O-ring can become, hard and brittle, from the heat of the engine. Damaged O-Ring Causing Injector Leak. If it breaks, then fuel can leak out, over the engine.
How to keep injectors in good health?

Why does my car stall on low RPM?
It’s because the fuel injector may spray too much or too little fuel, which creates a lean or rich mixture, which may cause the engine to misfire and stall.

Check Engine Light. One of the most obvious symptoms is that the check engine light on your dashboard is blinking. If one of the fuel injectors is clogged or dirty and is not efficiently supplying fuel to the engine, an electrical signal is sent to warn the driver.
Why does my car engine misfire?
The engine will misfire if the fuel injector is dirty, clogged, or does not open properly. An engine with misfiring will interfere with acceleration, reduce fuel efficiency, and result in loss of power. This requires immediate attention, as your engine could also start knocking and cause serious damage to your engine.
Why won't my car pass the emission test?
If the fuel injectors spray pattern changed and injecting too little or too much fuel into the engine, your car will most likely not pass the emission test. This is because too much fuel or too little will be enough to increase the emissions, and the catalytic converter will not be able to do its job properly.
