My vehicle is idling rough, what does it mean?
One of the early indicators of a problem with your vehicle’s health is when it’s idle. Many issues can result in a rough or bouncy sensation when the engine is running, and fortunately, some of them are simple problems which are quick and easy to fix. But in some cases, these issues are much more serious, and a rough idle may be an early indicator that it’s time to take your vehicle in for service.
We’ve run down some of the more common issues a rough idle may be a symptom of, but be sure to book an appointment with your Go Dodge Red Deer service department for a diagnostic, today.
A component of modern fuel injection systems is a vacuum, which helps the vehicle’s computer regulate the engine. Regular use of your vehicle’s vacuum system can result in hoses becoming loose or broken, which can cause fuel intake issues resulting in a rough idle. A quick glance in the engine compartment can show you if there’s any wear-and-tear on your vacuum lines. A vacuum leak should be repaired as soon as possible, so the problem doesn’t turn into a more serious issue.
Incorrect Idle Speed
The average idle speed of your vehicle is actually adjustable and is usually set to a standard around 1,000 RPM. Issues with the engine may have caused this to slip, resulting in your rough idle. While this may be caused by a more serious problem with your vehicle, it could be that your ride just needs to have the idle speed setting adjusted to correct the problem. Fortunately, this is a pretty easy fix our trained service technicians can take care of for you.
Dirty Filters or Pumps
Your standard combustion engine needs to be fed two things to run; air and fuel. Before either makes its way to your engine, your vehicle filters them to get rid of nasty contaminants which may cause damage. Over time, filters get clogged up, reducing the amount of fuel reaching the engine, and this could cause a rough idle. The good news is filters can be replaced during regular maintenance! But the bad news is if you don’t replace a clogged fuel filter in time, it can cause more costly damage to your fuel pump. Don’t forget, your fuel pump and fuel injection system can get just as dirty and clogged up as the filters too, and need occasional service to keep them delivering gas to the engine.
Your engine needs to burn fuel to run and spark plugs are the ignition source for your fuel. If a plug or plug wire has malfunctioned or was incorrectly installed, the engine won’t be able to process the fuel correctly. As your engine struggles to efficiently burn fuel, it will begin to idle roughly. Older models may also still be using a distributor cap to regulate the order your cylinders fire in, and a malfunction there can also cause a rough idle. The longer this problem persists, the worse it will get. A service technician should be able to replace a failing electrical component in the engine and get your vehicle running smoothly again.
