That smooth, powerful and quiet ride you have enjoyed with your Infiniti is becoming a distant memory - and you suspect that your Infiniti fuel injectors are the culprits. The Infiniti fuel injectors have the task of delivering fuel in the right fuel-to-oxygen ratio to the engine, ensuring that the proper combustion occurs at the right time. When fuel injectors begin to fail, you will notice engine misfires, knocking, loss of power and a drop in your gas mileage. You risk failing an emissions test because of the high levels of hydrocarbon and carbon monoxide emissions that come as a result of unburned fuel passing straight to your exhaust system. Detonations will eventually jar your engine so badly that damage might occur there. Detonations happen when the Infiniti fuel injectors fail to provide the proper mixture of oxygen and fuel, and combustion cannot be sustained during the combustion cycle. Infiniti fuel injectors depend on the on-board computer and other sensors to fine-tune how much fuel to supply to the cylinders. When the circuits leading to the sensors or computer fail, the combustion cycle can suffer. Alternatively, the Infiniti fuel injectors might not be providing the correct spray pattern. Age might be to blame for that: aging fuel injectors tend to drip instead of spray. Or, they simply become clogged with the fuel residue that is the remnant of your engine operations. When you diagnose that your Infiniti fuel injectors have, indeed, begun to fail, then order a new set here and replace them with quality, brand-name components.
