Idling Problems on an Infiniti

Add fuel injector cleaner when you fill your Infinity with gas to help with low idling problems.

Launched in 1989 by Nissan Motor Company of Japan, the Infinity brand of cars are designed to be a luxury version of the cars manufactured by Nissan. While the cars are known for the same level of quality that is associated with Nissan, they do from time to time suffer from an idling problem. Typically, the issue is either the engine is idling too high or too low.

Instructions

1. Remove and replace the fuel filter for your Infinity automobile. Internal combustion engines require the correct amount of fuel and air mixture in order for them to run properly. If the fuel filter is plugged, it may be restricting the correct amount of fuel from entering the engine, thus causing it to idle too low.

2. Add fuel injector cleaner to your gas tank. Infinity engines are fuel injected and these injectors can become slightly plugged or "gummed" up over time. Using a fuel additive designed to remove this blockage should improve the idling of your Infinity.

3. Replace the "Idle Air Control Valve" on your Infinity car. Before you do this, you should have the vehicle inspected on a mechanics diagnostic scope. The "Idle Air Control Valve" is an electronic device designed to control the amount of air that is circulating in the engine. If it is not working correctly the engine may idle at low RPM's (revolution per minute) or very high RPM's. When you change the valve, inspect the wiring harness that plugs into it. Look for any indication of an electrical short.
