Fuel injectors regulate the amount of pressurized fuel used for each engine cycle, and there is one injector per cylinder in an engine. When a fuel injector fails or clogs, engine power is reduced and misfires can occur. Other symptoms of a faulty fuel injector include the check engine light turning on, and the engine may stall immediately after starting, fail to start, hesitate under throttle, or vibrate roughly.

It is not recommended to drive a vehicle with a fuel injector problem, as these issues can cause unpredictable acceleration and stalling. If the problem is severe, the vehicle may not start at all.

Fuel injectors typically fail after 80,000 miles and require little maintenance. To prolong the life of fuel injectors, it is important to follow the scheduled maintenance routine for cleaning the fuel delivery system and injectors.

Symptoms of a bad fuel injector

A fuel injector is a device that sprays atomized droplets of fuel into the engine's intake manifold or combustion chamber. When a fuel injector fails or gets dirty, it can cause various issues with your vehicle's performance and fuel efficiency. Here are some common symptoms of a bad fuel injector:

Engine Misfires and Rough Idling:

• A faulty fuel injector may cause the engine to misfire, making it feel like the motor is sputtering and sending vibrations through the car.
• Rough idling is often characterized by varying revolutions per minute (RPMs), even when your foot is off the gas pedal. It can also be accompanied by engine stalling, where the engine suddenly stops running.

Poor Gas Mileage:

Well-functioning fuel injectors help your vehicle achieve optimal fuel efficiency as advertised by the manufacturer. If you find yourself visiting the gas station more often than usual, it could be a sign of dirty or faulty fuel injectors.

Engine Won't Start:

Fuel injectors deliver fuel to the engine, and if they are not functioning correctly, the engine may not start. This could leave you stranded and unable to operate your vehicle.

Check Engine Light:

The check engine light on your dashboard could illuminate due to various issues, including problems with the fuel injector. It may indicate that the fuel injector is dirty or malfunctioning, leading to an insufficient or excessive supply of fuel to the engine.

Fuel Leak:

Over time, heat and moisture can cause cracks in the rubber seals or the fuel injector itself, leading to a fuel leak. If you notice any leaks, it is crucial to inspect the fuel injector for damage.

Loss of Engine Power:

A bad fuel injector can starve your engine of the required fuel, leading to a loss of power. You may find it challenging to accelerate or maintain speed, especially when trying to overtake another vehicle or driving uphill.

Excessive Exhaust Smoke:

A malfunctioning injector can cause an overly rich fuel-air mixture, resulting in unburned fuel flowing into the exhaust system. This unburned fuel may exit through the tailpipe as black smoke.

Erratic RPM Needle:

Dirty or faulty fuel injectors can cause the needle on the tachometer (RPM gauge) to move unpredictably, indicating changes in RPM when your car isn't shifting gears.

If you notice any of these symptoms, it is essential to have your vehicle inspected by a qualified mechanic or technician. They can diagnose the issue and recommend the necessary repairs or replacements to get your car running smoothly again.

How to install a fuel injector

The cost of changing a fuel injector on a 2005 Honda Civic can vary depending on location, with prices ranging from $350 to $399. The cost of parts is between $213 and $226, and labor costs are estimated to be between $137 and $173.

Now, here is a step-by-step guide on how to install a fuel injector:

First, it is important to relieve the fuel pressure and depressurize the fuel system. This can be done by briefly running the engine with the fuel pump fuse removed. It is also recommended to let the car sit for a couple of hours without turning the ignition key. Additionally, for safety, it is best to wear protective eyewear and gloves when working with fuel.

Next, locate the fuel injector that needs to be replaced and disconnect the electrical connector by releasing the safety clip and gently pulling upward. These connectors are designed to keep moisture out, so they may be a little stuck. If this is the case, work the connector back and forth to loosen the seal.

On direct injection systems, use a line wrench to slowly loosen the injector line to relieve fuel pressure. Have a shop towel ready to cover the fuel release, as a small amount of fuel will be present.

Remove the fuel rail mounting bolts and lift the rail to separate it from the injector. Some systems have injector retainer clips that hold the fuel injector in place, in which case the injector will be removed with the rail.

Using a small screwdriver or pick, remove the retainer clip from the fuel injector and work the injector out of the rail. Keep a shop towel handy to catch any excess fuel.

Inspect the old fuel injector and make sure the sealing O-rings are accounted for. Match the new injector to the old unit. Some injector replacements may look different, but this is normal.

Lubricate the O-ring seals with clean engine oil to prevent damage during reassembly. Push the new injector into the fuel rail and reinsert the retainer clip. Tighten the fuel rail back into place and reconnect the electrical connector.

Finally, start the engine and use a flashlight to check for leaks to ensure the installation was successful.

Please note that this is a complex procedure and it is recommended to seek the help of a professional mechanic.
