Petrol injector cleaning and testing (fitting service parts and report where appropriate) - £12.50-14.50 per injector (most types).
According to Angie's List, the average cost of a fuel injector cleaning ranges between $50 and $80. However, these figures could be a bit higher, depending on the make and model of your vehicle. In addition, you may be assessed a fee of around $50 if your fuel filter needs to be replaced.
CARS.COM — Cleaning fuel injectors is a service frequently recommended by dealers and repair shops. But unless there are noticeable signs of clogged fuel injectors (such as a rough idle, stalling, poor acceleration or high emissions levels), it might not be necessary.
As mentioned, the average cost of fuel injector replacement can vary depending on several factors, such as the make and model of your vehicle, the severity of the issue, and your location. However, on average, you can expect to spend anywhere from $500 to $2,500 for this fuel injector replacement.
Age and condition – if the injectors are old or worn out, a clean may not be enough to restore performance and could do more damage. Severe clogging may mean they need to be replaced anyway. Costs – cleaning fuel injectors is cheaper than replacing them.
As mentioned earlier, when the injectors become clogged, they lose their ability to supply the necessary amount of fuel or create a proper spray pattern, but worse yet, the corrosive nature of carbon deposits literally destroys fuel injectors over time.
While fuel injector problems usually give warning, driving your vehicle for a long time with a clogged or faulty fuel injector can cause problems. At Rislone, we always advise customers to closely monitor how their engine is performing as a guide to determine if something might be wrong with their fuel system.
If the fuel injectors are clogged, your vehicle will not be getting the gas it needs to generate the power to go faster. The result is a sluggish response to your acceleration commands, including when you are stopped or when you are trying to pick up speed on surface streets or highways.
"Fuel injectors have an atomizing nozzle that distributes fuel evenly for optimal combustion and efficiency." Now, a vehicle will typically have one fuel injector per cylinder, with a lifespan of between 50,000 and 100,000 miles, or about 80,000 and 160,000 kilometers.
This fuel mixes with air, and then a spark is added and BOOM, combustion. An “injector service” is nothing more than running some cleaning fluid (called “fuel injector cleaner”) thru your injectors. The fluid that dealerships will use is the same stuff you can buy yourself and your local auto parts store.
Most popular Injector cleaning methods:
Injector / Injection Cleaner (Pour into fuel tank) Rail Induced Injector Cleaner (Used by repair shops and most dealers) DIY Injector Cleaning. Ultrasonic Fuel Injector Cleaning.
A clogged injector is not a safety concern, but it does starve the vehicle causing it to run poorly. Prolonged fuel starvation can lead to internal engine damage or damage to the catalytic converter. Fuel injectors can be inspected and tested to determine if they should be replaced or cleaned.
Fuel system cleaning cost can vary wildly from about $20 to over $1000. The variance in cost has a lot to do with what sort of cleaning you decide to use.
The most common fault codes associated with a clogged fuel injector are P0171 and P0174, which indicates the engine controller is seeing a lean condition. It is also possible to see fault codes for a rich condition if the injector is leaking or not atomizing correctly.
Once the injectors itself or the filter basket becomes clogged, no amount of intake or fuel rail induced injector cleaner will resolve the problem. The only and most effective way to deal with a clogged fuel injector is to remove it from the engine and have them professionally cleaned.
Depending on the engine and your skill level, it can take anywhere from 30-60 minutes. It requires hooking up a pressurized fuel cleaner to the engine's fuel rail and running it through at the recommended psi until the injectors are clean.
With the proper fuel injector cleaning equipment and chemicals it takes the professionals about 45 – 60 minutes of actual cleaning time to clean a single or set of fuel injectors. During this time the injectors are opened and closed 20 000 to 30 000 time whilst they are inside an ultrasonic bath.
Common causes of injector failure
While many things can cause breakdowns, the most likely cause of premature failure is fuel contamination. Fuel contamination occurs when debris in the fuel gets past the filtration, destroying the sealing surfaces.
Chevron Techron Concentrate Plus Fuel System Cleaner
It's an entire fuel system cleaner that claims to clean, restore, and protect not just your fuel injectors but carburetors, intake valves, and combustion chambers. It also won Autoweek's 2019 Reader's Choice Award for Best Fuel Additive.
Fuel injectors should be cleaned at least once every 36 months, or 45,000 miles. Replacing weak or worn-out engine parts without improving performance is not a good idea in general. However, cleaning out dirty injectors may gain a different perspective on engine health.
