How To Tell If You Need A Tune-up

Engines periodically need to be re-tuned to the original factory standards. This is primarily done by replacing some worn parts. For the most part, the adjustments older vehicles would require are no longer necessary as the computer handles the adjustment of the fuel mixture and the idler controller. In fact, there are only a few parts that need to be changed during the process of a tune-up.

Due to the self-adjusting computer system, vehicles are no longer required to be tuned up every 10,000 miles or so. It is much more common to have the tune up done every 50,000 miles or more. It is important to check your owner’s manual to find the appropriate mileage to have this done at. Of course, this is compounded by the factors of if you are performing a lot of stop and go driving. Another factor is if you are doing a lot of towing with heavy loads. This can require more frequent tune-ups for your vehicle.

There are several signs that you need to pay attention to that may trigger you to recognize that a tune-up is required. Most of the issues are caused by parts such as the spark plugs, air, and fuel filters, and PCV valve being worn. The motor running roughly when accelerating is one of the first signs that you will recognize. Typically, you will feel your engine accelerating unevenly or sounding like the firing of cylinders are not equal in time.  This could also happen when you are at an idle. A secondary issue that could occur is your vehicle becoming harder to start.

Taking your vehicle to a certified service center such as those at Reedman Toll of Drexel Hill will provide you the comfort that your vehicle is being tuned to your manufacturer’s specifications.
