Your Hyundai Accent's fuel injector is engineered precisely to create a fine mist of fuel for easier burning. However, due to all sorts of fuel problems that may range from clogging to leaking, the fuel injector may lose its efficiency. If you think your fuel injector is already worn out, then you had better make time for troubleshooting to keep your car in top shape. Here are some of the problems and their causes that you may encounter on your Hyundai Accent fuel injector.
Did your oxygen sensor read your fuel mixture as lean? It may be caused by a malfunction in the sensor, or it could also mean that fuel deposits have clogged up your Hyundai Accent's fuel injector. You see, the accumulated deposits can restrict fuel delivery and disrupt the fuel injector's pattern, which then causes an imbalance to the air and fuel mixture. When this happens, be sure to make time for repair or you will have to deal with more engine and emission problems.
If you find reduced fuel output and engine performance, then the gas in your fuel injectors may have been contaminated by rust, water, oil, and other substances. You see, there are simple ways to diagnose contamination. If you suspect water to be the contaminant, you may use calcium chloride to absorb it in the fuel. There are also several tests you can perform to detect contamination. Some may require the use of modern equipment while some require only the comparison of densities and observation of residue.
If you find fuel coming out from the exhaust pipe, then you probably have a leaking fuel injector. You see, the leaking from the fuel injector will cause the cylinders to malfunction. And with that, you will find the exhaust gases to smell of fuel. Once these symptoms are present, you should unplug the fuel injector harness and plug wires and visit a car shop to avoid further engine problems.
If you have the time and budget, a number of auto parts stores offer mechanic's stethoscopes, digital ohmmeters, and nod lights to make it easier to diagnose faulty fuel injectors.
