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.
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.
The only guaranteed way to unclog a clogged injector properly is by removing the injectors from the engine. Once removed, the injectors can be dropped off or mailed to a professional injector cleaning service such as Injector RX.
Yes, a bad fuel injector can damage your engine so badly that the vehicle cannot run again until it is fixed. Normally before a bad fuel injector would cause damage to your vehicle engine it would give you so many signs and symptoms like the one, we have discussed above.
Replacing a Fuel Injector is definitely not cheap. It will differ quite a bit based on where you live, what brand you want to use and where you install it. But you can expect to pay up to $350. The parts themselves are up to $200 at most, so the rest will be installation and labor related to this process.
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.
Rough idling is a sign that your automobile's engine is not getting enough gasoline, and one reason why it might not be getting enough gas is that your fuel injectors are clogged. You will feel your vehicle vibrate as you sit at an idle, and you may hear the engine cutting in and out.
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. That occurs when particles build up on the injector nozzles, thus affecting the amount of spray and atomization of fuel.
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.
Aside from the fumes and fuel itself, the fuel injectors can get clogged up by debris. This can either come from gas or from the fuel system itself. Gasoline with impurities in it is less common these days, and most major gas stations have consistently high-quality gas.
The fault codes usually associated with a clogged fuel injector can range from misfire codes to lean codes. Fault codes associated with a clogged fuel injector are the P0300 thru P0308 series, which indicates the engine controller is seeing an engine misfire.
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.
In general, they're expected to last a pretty long time. Both Bosch and Delphi, two major manufacturers of automotive components, say their fuel injectors have a life expectancy of 1 billion cycles. Essentially, that means that the fuel injectors should last as long as the car does.
On average, you can expect to pay between $350 and $850 to replace your fuel injectors. The range of costs depends on a number of factors. Smaller vehicles with fewer cylinders requiring less expensive parts will come in at the lower end of the spectrum. Larger, high-performance engines will command a higher price tag.
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.
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.
If your vehicle fails an upcoming emissions test, it is likely a sign of clogged fuel injectors. Engine stalling - If your engine doesn't receive a proper air to fuel ratio, it can cause your engine to stall or hesitate. Rough idling - Your car may also notice negative side effects when it doesn't move.
Is it worth adding to your gas tank? 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.
Use a fuel injector jumper in order to open up the fuel injector, then spray your cleaner through each side of the fuel injector. Once you're finished cleaning, you can reconnect your fuel injectors, reconnect the fuel pump, and re-start your engine.
Clogged Fuel Injectors
Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris. Once clogged, the fuel injectors may not add the correct amount of fuel to the cylinders, and the vehicle may not start up at all.
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. Think microns, smaller than a human's hair-sized, clearances.
There are two methods for cleaning your fuel injectors. The first is just using an over-the-counter fuel injector cleaner to try and flush your injectors out. The cleaners have detergents that can break down gunk and they're applied to the fuel tank, so they can run through the injectors along with the fuel.
In normal driving conditions, the Fuel Injectors should be changed every 50-100k miles.
