About Fuel Injector Repair

A damaged fuel injector can prevent fuel spray into your car's engine or disturb the intervals at which it is supposed to function. When fuel injectors get dirty with engine gunk, carbon and fuel additives – you must consult an expert before your car’s engine begins to malfunction.

How do you know if your car's fuel injector is bad?

Engine light comes on

The most common signal of a bad fuel injector is the engine warning light on the dashboard switching on. The warning light is triggered when the injector delivers too much or too little fuel. However, this does not necessarily mean that there’s an issue with your injector, the engine light can signal the wearing out of other auto parts as well.

Engine stalling

If your car engine randomly stalls chances are the fuel injectors are unable to do their job of delivering adequate fuel to the engine. Engine stalling can occur when the injector nozzles are blocked or when there’s a fuel leak.

Misfiring engine

When a clogged fuel injector fails to deliver the right dose of fuel, the fuel-air ratio in the combustion chamber is disturbed, causing a misfire or a sudden drop in acceleration. This problem needs immediate attention as the engine will be susceptible to overheating or other problems.

Surging engine

When too much gasoline is injected into your engine, it will automatically adjust air intake, fuel injection timing to get everything back in line. This causes the engine to surge too fast and then accelerate slowly.

Fuel leak and odour

Your car’s fuel injector may leak gasoline if it develops cracks because of old age or damage. If leakage occurs, you will get to smell the fuel strongly while driving and you might also notice fuel all over the injector or on the nearby fuel rail. Seek an expert’s help as soon as you discover leaking injector symptoms.

Vibrating engine

A bad fuel injector will hamper the functioning of the corresponding cylinder. Hence, every time you drive, your engine will either vibrate or experience a hiccup as the engine completes each cycle.

Poor fuel economy

If the fuel injector is failing, your car may consume more fuel than ever. This happens when the ECU calls for more fuel from the injector but is unable to receive it in the combustion chamber. The less fuel reaches the engine, the lower is your vehicle’s fuel economy. You may also experience this problem if the injectors are leaking or are clogged.

Increased emissions

A damaged fuel injector can cause an uneven or incomplete fuel burn, resulting in increased emissions. When an injector isn’t delivering fuel as it should, the fuel-air mix in the combustion chamber gets upset. As a result, some fuel isn’t burnt off and more harmful emissions are sent to the exhaust system. Book our injector cleaning services if you wish to improve the injector’s fuel delivery and reduce your emissions.

How long should fuel injectors last?

Fuel injectors can last between 50,000 and 100,000 miles depending on how well you’ve maintained your car. Not changing your fuel filter regularly, filling cheap or unreliable fuel and repeated stop-and-go driving circumstances (driving in heavy traffic) can add up to a premature fuel injector failure.

When to replace fuel injectors?

While fuel injector cleaning services can help restore your car's performance by enhancing its power and mileage, it can't improve your car beyond its original specs. Dirty or worn-out injectors can cause preignition or detonation when the air and fuel combust before the spark plug fires, damaging the pistons and causing severely increased engine temperature. Leaky injectors can cause your car to flood by shutting the engine with excess fuel trapped in the system. A bad injector can wreak havoc on your car’s engine and should be replaced immediately to restore functionality.
