Spark Plug Service and Replacement at Griffith Ford San Marcos

There can be a number of reasons as to why your car won’t start, from your battery to your wiring. If your spark plugs are the issue, this certainly isn’t a repair you’re going to want to make at home, as they can often be extremely difficult to get to and require very specific sizes to replace. When you’re around Austin, Fredericksburg, or San Marcos, and you’re looking for quick and comprehensive service, you’re going to want to visit Griffith Ford San Marcos. 

What Your Spark Plugs Do

Your spark plugs help to ignite both air and gasoline inside your engine and are integral to your combustion cycle. They work with the help of your ignition coil, which funnels electricity from your battery. At just the right moment, your spark plugs will draw on this power to fire up a spark. The amount of spark plugs your model has depends directly on how many cylinders there are in your engine, as you’ll have one for each. When your spark plugs are working well, they should offer you the perfect pairing of power and mileage. This efficiency also helps to keep your emissions low, so if you find that you fail your state’s emission testing, this could be one of the reasons. 

Signs of Trouble

There are multiple signs that can point towards worn spark plugs, so you can hopefully catch the issue before it spirals into something bigger. If your vehicle has a rough idle or you notice a drop in power, your engine might not be functioning as well as it normally would. You may even have engine misfires if they become too worn, which can damage other parts of your engine while also causing your catalytic converter to overheat. Your owner’s manual will generally give you a guide as to when you should replace your spark plugs, but if you find that you’re experiencing any of the above symptoms, you’re going to want to take your vehicle in so that you can have them inspected. Damage to your spark plugs can not only be extremely inconvenient when it comes to performance, but it can also be detrimental to the other expensive parts of your engine.

What’s in a Service?

Changing your spark plugs can be daunting, as you’re going to need the exact size for your model and it isn’t a particularly easy part to get to depending on your model. When you’re dealing with your engine directly, you’re going to want to make sure that everything is done correctly. When you bring your vehicle in for service at Griffin Ford San Marcos, our mechanics can not only easily replace the part, but will also take your vehicle for a test drive to ensure that everything is working correctly before you get back on the road. This can help catch other issues your vehicle may be having so that you can get ahead on repair bills. Generally, all of your spark plugs are replaced at once, so you won’t have to worry about needing another service for quite a long time.
