When you pull up to a red light, your vehicle should stop and come to a smooth idle. You shouldn't notice much from your car besides the stereo and the low hum of the engine. The dashboard usually alerts you if there is a problem, but it may not always come through. One sign that there may be an issue is your vehicle starts to vibrate while it's idling. A rough idle can leave you concerned and scratching your head. To help pinpoint the cause, below are three common reasons your vehicle may have a rough idle.
Dirty Air Filter
Your vehicle needs oxygen to function, so the engine filter is in place to prevent dust, dirt, and debris from entering the engine. The filter doesn't stay clean for long; as you take on the road, it gets filled with pollutants. The engine filter should be checked during routine oil changes and should be regularly replaced. If you go too long without replacing the engine filter, you'll notice a hit to your vehicle's performance with rough idling.
Clogged Fuel Injectors
It's a no brainer that your vehicle needs fuel to drive. Over time, impurities can become tacked to fuel injectors, preventing them from spraying insufficient amounts of fuel. Cleaning the fuel injectors can restore performance. Neglecting the fuel injectors can leave your vehicle vibrating with each stop.
Worn Spark Plugs
Spark plugs give the spark that completes the combustion process. The spark is composed of wires, plugs, and coils that ignite each cylinder within the engine. Spark plugs should be replaced every 30,000 to 50,000 miles because with time; the coils can break down. Spark plugs that have worn can cause rough idling and, in severe cases, a misfire.
