6 Signs That You Need New Spark Plugs

September 11, 2019

Though they are small and relatively simple in design compared to other automotive components, spark plugs play a very important role in the overall health and performance of your vehicle. If any of the spark plugs are dead or not working right, your engine will struggle and it may not fire up at all. Spark plugs need to be changed out periodically and tested regularly to ensure they are doing what they are supposed to do.

Here are 5 of the most common signs that you need new spark plugs, according to the Colorado Springs automotive repair specialists at LightHouse Automotive :

1. The Car is Struggling to Start

This is an obvious problem that you will want to get looked at. It may be a failing spark plug or something wrong with the ignition, fuel system , alternator, battery or engine itself. When the vehicle is struggling to start up in the morning, it's a clear sign that something is wrong. A good mechanic will be able to identify the specific issue and recommend the necessary repairs. The best case scenario is a bad spark plug that is easily replaced.

2. The Engine is Idling Roughly

Rough idling is another sign that the engine isn't firing on all cylinders and that one or more of the spark plugs could be getting weak. 

3. Poor Fuel Economy

If you notice you are not getting very good gas mileage (compared to what you normally expect), there are any number of automotive issues that can be causing the problem. The spark plugs could be the culprit, but it is worth getting your vehicle inspected to identify any other potential causes.

4. The Engine is Misfiring

This may go hand-in-hand with the rough-idling engine as noted in #2 on this list. You may hear some loud pops, bangs and misfiring sounds coming from the engine. This is generally because of a poor spark plug or a poor wiring connection that isn't allowing the cylinders to fire up in the perfect unison that they need to. 

5. Sluggish Acceleration

A faulty spark plug can lead to the vehicle feeling very sluggish when you try to accelerate. This could also be a transmission issue or something else, though, so again it is best to have a professional look at the car and get to the root of the problem. 

6. Corroded Spark Plugs or Connections

If you are able to actually look at the spark plugs under the hood, you may notice they look corroded or crusty. This is a common sign that they need to be replaced sooner rather than later.

Whether your spark plugs are the problem or something else, LightHouse Automotive is here to help you determine the source of the issue and recommend the necessary repairs. If you are experiencing any of the symptoms above or anything else that doesn't seem right with your car, call our Colorado Springs auto repair shop today at (719) 465-0302 or schedule your appointment online.
