Fuel injectors are engine management components found in many vehicles. They’re part of a car’s fuel system. Fuel injectors act as nozzles which spray fuel into a car’s engine. The engine computer controls them. They operate by spraying fuel in particular patterns and at precise timed intervals that optimize the engine performance.
Since fuel injectors make the fuel system of any cars, any problems associated with them can result to different engine performance issues. Sometimes, such issues can render a car undrivable. Normally, a failing or bad fuel injectors produces a number of symptoms which can alert you of a prospective issue.
The following are some of the symptoms of a clogged fuel injector:
Symptom #1: The Engine Misfires and Decreases in Fuel Efficiency, Acceleration and Power
Engine performance issues are the most common symptom of a clogged fuel injector. When it happens, the air fuel ration of an engine gets upset hence resulting to performance problems. Faulty fuel injectors can cause a car to experience loss in power, misfires, a decrease in fuel efficiency, acceleration etc. In severe cases, it causes stalling or prevents your car’s engine from functioning at all.
Symptom #2: Fuel Odor
Fuel smell is the other common symptom of an underlying issue with a fuel injector. Injectors normally hold high pressures that over time can make them leak mainly at the nozzle. Leaky injectors pass excess fuel to the engine’s chamber engine. A leaky seal on the other hand leaks fuel at the injector’s base. Both of these situations affect the performance of the engine, specifically fuel efficiency. Both of them normally produce noticeable fuel smell. It is prudent to address any form of fuel smells immediately you notice them. It goes miles in preventing them from turning out to becoming potential safety hazards.
Symptom #3: Check Engine Light Comes On
An illuminated check engine light is another indication of a potential issue with your vehicle’s fuel injector. If a fuel injector is clogged and causes a misfire or even experiences an electrical issue, your car’s computer will set off check engine light in order to alert you of the problem. The light can also come on due to many other engine management issues. Consequently, it is highly recommended that you have a computer scanned for trouble codes.
When the clogging of a fuel injector gets severe, your car will suffer from the following issues:
l Increased combustion
l Failing emission tests
l Engine stalling/rough idling
l Performance loss
l Engine misfire
l Engine stumbling, hesitation and stutter
Because of the important role as nozzles that offer fuel enabling the engine to run, your car’s fuel injectors are crucial components to the overall functionality and drivability of a car. If your vehicle displays any of the above symptoms or you merely suspect that the car might be having an issue, it is highly prudent you have it diagnosed by a professional technician. Doing so will help determine whether any of your car’s fuel injectors needs replacement.
Alternatively, before contacting a technician, after determining that your car’s fuel injector has a problem, you can check these injector cleaning methods.
