The smaller parts of your vehicle might not seem like an issue, and most of the time, many people don’t even notice when an issue is present — but these small quirks might be the predecessor to a larger issue. One of the things that goes unnoticed is a fluctuation in RPM’s whether at idle, or when driving. While many won’t see them, it should certainly be checked on every once in a while. Below are a few explanations as to what might be the issue and cause for that fluctuation.
Spark Plugs
In older cars, your spark plugs might just need replacing. A quick tune-up can greatly help the engine performance of your car and how it operates when it’s at idle. Things like your plugs, distributor cap and more are all small factors that can contribute to making a big difference down the line.
Vacuum Leak
If you’re noticing more fluctuation than normal, it might be worth it to check for a vacuum leak in your car, which happens inside the engine bay. While you might not be able to diagnose this yourself, louder leaks are sometimes more easily noticed and can be heard by almost anyone.
Major Engine Issues
If your fluctuation in idle is also happening with rough engine idles, shaking or any other unexpected issues, it might be worth taking your car to a shop to have it properly diagnosed. The last thing you need is a major issue that strands you on the side of the road, or leaves you with a hefty bill. Keep this in mind for anything you see or feel out of the ordinary.
