Dirty fuel injectors may cause your vehicle's engine to misfire. This problem makes the motor feel as though it is sputtering — sending vibrations through the car. Such misfires can happen when a fuel injector problem mixes up the delicate balance between fuel and air entering the engine.
If you have one or more faulty fuel injectors — due to wear or mechanical or electrical issues, driving for a long time can cause several problems: Stalling or failure for your car to start. Flooding of your engine. Pre-ignition of your fuel.
If your injectors are dirty and/or clogged, your vehicle's engine might misfire. This will feel as if your engine is sputtering, which will make your vehicle lurch or vibrate. Your engine is misfiring and sputtering because the fuel injectors are not providing enough fuel for the air/fuel mixture.
Your vehicle's fuel injectors directly affect its performance. Most automobile manufacturers recommend you have the fuel injectors cleaned every 15,000 miles. You can go as long 30,000 miles in most cases or, if you don't drive that many miles each year, your fuel injectors should be cleaned once a year.
Although fuel injectors are an important maintenance service for your vehicle, they are a relatively affordable service that most people can add to a standard oil change. The average cost of a fuel injection service ranges between $50 and $80 dollars depending on the model and make of a vehicle.
Injector Replacement or Injector Cleaning? 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.
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.
In short, when used regularly, fuel cleaners work. They can help remove harmful deposits, prevent new deposits from forming, and enhance vehicle performance. Fuel additives can improve gas mileage, reduce long-term maintenance costs, and they're affordable.
Rough Idling/Irritating Idle Noise
Typically, a car delivers a subtle rumble when at idle. If you notice that the sound has gone from low to a rough and unpleasant noise, it may be a sign of bad fuel injectors.
"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.
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.
Your car may sputter or shake, mostly during traffic stops. The engine idling is mainly due to inconsistent revolutions per minute (RPMs). A sudden decrease in fuel supply, especially during uphill climbing, may accompany rough idling. Sometimes, you may have to restart the car due to insufficient fuel supply.
One of the obvious symptoms of a clogged fuel injector is the lighting up of the "Check Engine" light in your dashboard. The fault codes usually associated with a clogged fuel injector can range from misfire codes to lean codes.
For the first dose, simply install when you have a full tank of gas. It's that simple. From there, many experts will probably tell you that you should add a fuel injector cleaner to your gasoline every time you fill your tank up.

The Engine Misfires
Dirty fuel injectors may cause your vehicle's engine to misfire. This problem makes the motor feel as though it is sputtering — sending vibrations through the car. Such misfires can happen when a fuel injector problem mixes up the delicate balance between fuel and air entering the engine.
Absolutely Yes. Fuel injector cleaners work in very diluted amounts, and twice the strength (same amount of cleaner in half as much gasoline) works just a little faster. After all, we're talking about 12 ounces of cleaner in 12–15 gallons of gas, so the ratio of cleaner to gas is 100:1.
Generally, we recommend that you clean your injectors every 15,000 miles. However, you could undoubtedly do it less frequently: about every 30,00 miles or once a year. You may also want to be careful about the gas you put into the vehicle and always check its quality beforehand.
When a fuel injector is clogged, it needs a concentrated cleaning to resolve the problem. This can be done by a qualified mechanic, or if you know your way around the inside of an engine, you can do it yourself. To start, invest in a fuel injector cleaning kit.
If you've noticed symptoms of injector failure while driving, don't delay! While the risk of severe engine damage is relatively low, it's not impossible. More importantly, replacing a bad fuel injector will improve the fuel economy, engine power, and overall drivability of your vehicle.
You can drive at least 5,000 miles or more with a bad fuel injector. But you should avoid driving with a bad fuel injector as it can damage other parts of the fuel system. You should not ignore bad fuel injector symptoms.
There's a good chance you will need to replace them at least once or twice. Fortunately, replacing your fuel injectors isn't typically a huge expense, unless they are part of a larger engine issue. Taking proper care of your fuel injectors will help prevent bigger problems.
