Sluggish. Squealing. Unreliable. Vibrating. If any of these descriptors fit your vehicle’s recent behavior, it just might be trying to tell you something – like it’s time for a tune-up.

Today’s vehicles differ significantly from their decades-old brethren that required a tune-up every 10,000 or 20,000 miles. With newer vehicles, it’s increasingly common for manufacturer-recommended service intervals to stretch to 100,000 miles before certain maintenance items, such as replacing the spark plugs, should be completed. 

Spark plugs have been around since the beginning, and play as important a role now as they did a hundred years ago. It’s a good idea to replace them as a set at regular intervals, but sometimes one will go bad sooner than the rest for one reason or another. How do you know if you have a bad spark plug? Here are some indicators, from WORKING CLASS AUTO AND DIESEL in Pell City, AL.

At WORKING CLASS AUTO AND DIESEL in Pell City, AL, we can help!

Tune-ups are an important and frequently neglected aspect of automotive care. Most drivers don’t really consider the mechanical condition of their car, so long as nothing is wrong with it. However, if a vehicle is tuned-up and maintained correctly, many mechanical failures (and expenses) will be avoided altogether. So whne is the right time to get a tune-up?
