COMPLETE ENGINE DIAGNOSTICS & REPAIR

Whether you’re running a few quick errands around Tyler or stuck in East Texas traffic, nothing puts a damper on the day like seeing your car’s Check Engine Light appear on your dashboard. There are a number of reasons that can cause this to happen. Before panicking, realize that there are many sensors on the engine, and a Check Engine Light can often have a simple, inexpensive repair. You might only need to turn your gas cap tighter or replace your car battery. Our AC Delco Certified technicians will be able to tell you if it is a quick fix or the sign of a larger issue. When your car, truck, or SUV tells you something is wrong, give our team with over 60 years of experience a call.

About Engine Diagnostics

Beginning in the mid 1990’s, almost all passenger cars have been manufactured with on-board engine diagnostic equipment (OBD) or in simpler terms, your car’s computer. Onboard engine diagnostic equipment communicates with the electronic sensors all over your engine. The signals sent back to each specific system’s computer alerts you if engine repair or maintenance is necessary. Although the information provided to you is vague, it’s actually a very helpful safety feature.

How Does an Engine Diagnostic Work?

It's a simple process. Our equipment allows us to "speak" with your vehicle’s computer. Using professional, state of the art diagnostic equipment, we connect directly with the onboard computer of your vehicle. The software will interface with the vehicle computer to reveal a diagnostic code, which is cross-referenced with a database of manufacturer vehicle codes. The code provides needed information to accurately identify the problem and implement the proper solution. After we complete the diagnostic, we will provide you with an auto repair estimate. We will never do any repair work without your permission first.

What Are the Most Common Engine Problems?

  • Loose gas cap
  • Failing oxygen sensor
  • Worn catalytic converter
  • Bad spark plugs and wires
  • Failing mass air flow sensor
  • Bad ignition coil
  • Bad exhaust gas recirculation valve
  • Faulty vacuum hose
  • Dying battery

If you do not see a Check Engine Light, but your engine is making unusual noises or you are experiencing poor vehicle performance, our experts will conduct a thorough engine diagnostic check to quickly pinpoint what part of the engine is malfunctioning. We will provide an engine repair estimate as well as a recommendation on how quickly you should address any issues. Even a simple car tune up or inspection from Stewart’s Donnybrook in Tyler TX can improve your vehicle’s performance and prevent you from damaging engine components that could lead to expensive repairs in the future.
