You can help your service facility by describing the problem in detail. Here's a list of things to make a note of:
- When is the problem happening, when the engine is cold or when it's been running for a while?
- Does the rough idling occur when I'm accelerating or when I'm going at a steady speed?
- Does it happen at high speeds? Does it happen at low speeds? Does it happen at both?
Make sure you describe the problem in as much detail as possible, as it will help a technician diagnose it.
One of the first things they'll check is how the spark plugs are firing. Modern iridium plugs are supposed to last a long, long time. But they CAN eventually wear out. Inspecting the firing end can help the technician identify the root cause of the problem. Corroded or worn-out spark plug wires can also contribute to an idling irregularity.
There are other potential problem spots, too. The technician may check the ignition coil, timing, piston rings, valves, and cylinder walls.
If the air-to-fuel mixture isn't correct, it may affect how smoothly your vehicle runs. Your service facility is equipped with diagnostic tools that help pinpoint the problem. Once that idle is smoothed out to the way it used to be, you'll be the smoothest operator on the road.
