Warning signs: engine stalling, shuddering, and poor fuel economy
Warning signs that your Honda CRV's fuel injectors may be faulty include engine stalling, shuddering, and poor fuel economy. Engine stalling can be caused by a lack of fuel, which is a common issue with faulty fuel injectors. This can also cause the engine to misfire, which can be felt as a struggle to accelerate or a hesitation after you press the accelerator. This can lead to the engine overheating.
A faulty fuel injector can also cause the engine to shudder or shake, which can be felt through the seat or steering wheel, especially when maintaining a steady speed. This is due to the affected cylinder not receiving the correct amount of fuel, disrupting the engine's normal firing sequence.
Poor fuel economy can be caused by a number of issues, including a loose gas cap, clogged fuel filters and fuel lines, or clogged injectors. A clogged injector will cause the engine to work harder to pull fuel through, resulting in increased fuel consumption.
Other warning signs of faulty fuel injectors include the "`Check Engine`" light illuminating on your dashboard, a reduction in engine power, and abnormal fluctuations in fuel gauge readings. If you experience any of these issues, it is recommended to have your vehicle diagnosed by a professional to determine the root cause and perform any necessary repairs or replacements.

Diagnosis: Honda technician will conduct a visual inspection and connect a computerized scanner
If you suspect that your Honda CRV has a faulty fuel injector, it is recommended that you visit a certified Honda technician to have the issue diagnosed and addressed. The technician will first conduct a visual inspection of the fuel delivery system and injectors. This involves physically inspecting the injectors, intake manifold, fuel rail, and other components. If the issue is not immediately clear, the technician will then connect a computerized scanner to the vehicle to read its sensors and check for any trouble codes.
The scanner will help identify if there are any misfires occurring and on which cylinder they are happening. The fuel injector or injectors in question will then be tested and may need to be removed for bench testing. If any issues are found, the faulty components must be replaced. For example, if the injector O-rings and seals are damaged or leaking, they should be replaced. If the gas cap is loose or damaged, it should be tightened or replaced.
In some cases, the intake manifold may need to be removed to access and replace the fuel injectors. This can be a large job, as it may involve draining the coolant and oil and removing many engine components. It is important to note that fuel injector replacement should be left to a professional due to the risk of fire and the complexity of the repair. The average cost for a Honda CR-V Fuel Injector replacement is between $836 and $990, but prices may vary depending on the specific vehicle and the labor involved.
Some symptoms of a faulty fuel injector in a Honda CRV include the check engine light turning on, the engine stalling, reduced engine power, engine hesitation or surging, and abnormal fluctuations in fuel economy. If you experience any of these issues, it is important to have your vehicle diagnosed and repaired by a qualified technician to ensure your safety and avoid further damage to your vehicle.
