There are people that are very comfortable working on their car or truck and making many basic repairs, but there are some repairs that require a visit to an auto repair shop for some professional help. In most cases, newer cars and trucks with their complex fuel and electrical systems require specialized tools and equipment that you most likely do not have but your local auto shop will.
Older cars were often easy to keep running pretty well. The engine tuning was limited to installing some spark plugs, wires, and a new distributor cap, but today's engines use advanced electronics to alter the tuning as you drive. The only way to truly tune these cars is to use an engine diagnostics system or computer, and in most cases, an auto repair shop is the only place you will find one.
The computers used to tune these vehicles are too expensive for the home mechanic to purchase, but an auto shop that is tuning cars daily needs to have the right tools for the jobs so they will have the computer and the proper software to access the computer on many different vehicles and make an adjustment to the system for you. The auto repair shop will be able to read the sensors in the system and determine if there are faulty parts that need replacing.
Without the proper equipment, tuning the engine the traditional way can actually make the engine run worse, so for newer cars, this is a repair that needs doing in a shop by a professional technician.
Fuel System Repairs
Fuel injection, direct injection, and hybrid fuel systems are becoming more popular as manufacturers look for more ways to improve the fuel economy and the power of modern cars. These fuel systems often require equipment that is only found in a repair shop to assess the condition of the system and make repairs to it.
If your car is running rough or is down on power, the fuel system may need to be checked, and the technician at the auto repair shop will start with a diagnostic check of the sensors and the computer in the car. The system has too many intricate pieces for most people to work on at home comfortably, but the auto shop can pinpoint the problem and make the repairs in less time and without having to replace parts that are working correctly.
Something as simple as a bad injector can cause the engine to run rough and use more fuel than it should, so if you suspect a fuel system problem on a fuel-injected car, taking the car to a shop for a check is your best option. Look for an auto repair shop in your local area.
