Have you noticed that your car, truck, or van feels rough and bouncy when the engine is running? That means that your vehicle has developed a rough idle. It’s not a normal condition and should be taken seriously. To help, take a look at some of these common reasons for rough engine idling.
One of the most common causes of a rough idling engine is a loose or broken vacuum hose. The job of vacuum hoses is to aid in the powering of various parts of your vehicle. Over time, they become more susceptible to wear and tear. Eventually, a leak can develop and cause your engine to misfire. As a result, your vehicle will develop a rough idle, usually at a higher RPM.
Your vehicle’s spark plugs provide the spark needed to ignite air and fuel mixture within the cylinders. This process is what keeps your vehicle moving down a road. Spark plugs that are left too long without being replaced can collect carbon deposits, oil, and ash. Therefore, reducing the amount of power that is produced when the spark plugs ignite. The vehicle then has to compensate for the lack of power and can result in damage to other ignition-related components. That is what causes the rough idle.
Today’s vehicles are equipped with fuel-efficient, high-pressure fuel injectors that spray the exact amount of fuel into each cylinder at just the right moment. They have spray nozzles with tiny openings, and these openings can get clogged from the carbon that is the byproduct of the process. When these openings become clogged, it leads to less fuel going through the injectors, noticeable poor performance, and rough idling.
Your vehicle’s air filters are responsible for keeping dust, dirt, and other debris from entering the engine. As the filter becomes clogged, it reduces the amount of airflow into the engine and causes a rough idle. That’s why it’s important to clean your vehicle’s air filter at least once a year. You can check your owner’s manual for exactly how often the manufacturer recommends changing your vehicle’s air filters.
