Fuel injectors regulate the amount of pressurised fuel used for each engine cycle. They require little maintenance, but they tend to fail after 80,000 miles. When they fail or clog, engine power is reduced and misfires will occur. The check engine light will turn on and, as the issue progresses, the engine may stall immediately after starting, fail to start, hesitate under throttle or vibrate roughly. The average cost for a Honda Civic Fuel Injector Replacement is between $350 and $403.

Fuel injectors tend to fail after 80,000 miles
If fuel delivery system symptoms are present, a technician will first conduct a visual inspection. If the issue isn't clear, they will connect a computerized scanner to the vehicle to read some of its sensors. If there is a fuel injector problem, misfires are likely to be happening frequently on one cylinder. The fuel injector or injectors in question must then be tested and may require removal for bench testing.
When a fuel injector fails or clogs, engine power is reduced and misfires will occur. The check engine light will turn on and, as the issue progresses, 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 this can cause the car to stall and accelerate unpredictably, creating a hazard.

Fuel injector replacement costs between $350 and $403
Fuel injectors regulate the amount of pressurised fuel used for each engine cycle, and there is one injector per cylinder in an engine. Each time an intake stroke occurs in the engine, the vehicle's computer will send a signal to the fuel injectors, requesting they spray fuel. For heavy acceleration, the duration of the fuel spraying will be longer than if the engine were idling. When a fuel injector fails or clogs, engine power is reduced and misfires will occur.
On average, fuel injectors tend to fail after 80,000 miles, and require little maintenance. To prolong the life of the fuel injectors, follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors. If fuel delivery system symptoms are present, the technician will first conduct a visual inspection. If the issue isn't clear after a physical inspection, the technician will connect a computerized scanner to the vehicle to read some of its sensors. If there's a fuel injector problem, the technician would most likely find that misfires are happening frequently on one cylinder. The fuel injector or injectors in question must be tested, and may require removal for bench testing.
It is not recommended to drive a vehicle with a fuel injector problem. Issues can cause the car to stall every few moments and accelerate unpredictably, creating a hazard. The check engine light will turn on and, as the issue progresses, the engine may stall immediately after starting, fail to start, hesitate under throttle or vibrate roughly.

A clogged fuel injector can cause engine misfires
Fuel injectors tend to fail after 80,000 miles, but some Honda owners have reported their injectors going strong after 180,000 miles. To prolong the life of the fuel injectors, it is important to follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors.
A clogged fuel injector can also cause a rough engine idle, with the vehicle performing normally under acceleration until the injector becomes completely clogged and creates a cylinder misfire. Deposits can form on the fuel injectors from fuel droplets that evaporate after the engine is shut off. These gum and tar-like deposits can clog an injector, skew its spray pattern, restrict the fuel flow, or prevent the fuel from vaporizing completely.
If you suspect a clogged fuel injector, it is important to have it checked by a technician. They will first conduct a visual inspection and, if the issue isn't clear, they will connect a computerized scanner to the vehicle to read some of its sensors. If there is a fuel injector problem, they will likely find that misfires are happening frequently on one cylinder. The fuel injector or injectors in question must then be tested and may require removal for bench testing.
