Engine Diagnostics in Southbury, CT

Modern vehicles are engineered to let you know when there's a problem through dashboard warning lights. Perhaps the most notorious warning is the Check Engine Light. As soon it turns on, you may find yourself wondering what's wrong and how much it will cost to fix it.

Your Service Engine light can turn on for many reasons. The cause could even be as small as a loose gas cap. If tightening the cap doesn't work, however, it's a good time to schedule an engine diagnostic.

Find Out What's Wrong with a Diagnostic

Understanding what's wrong with your car is important so you can make an informed decision about what to do next. No matter what's causing your problem, you can discover the answer with a diagnostic service at Corrigan Motors. You might also want to get a head start with our online diagnostic center.

Engine diagnostics are one of the many automotive services we provide for Southbury, Newtown, Woodbury, and surrounding areas.

We're also available for engine tune ups to help you keep your car running in top condition.

Need to make an appointment? Call (203) 264-9100 or contact us online.

The Engine Diagnostic Process

If there's a problem with your engine, it's likely your "Service Engine" light will turn on. This light will have a code associated with it. To translate the code, technicians at Corrigan Motors will connect a diagnostic tool to your car. Once the code is translated, our technicians can verify the cause and provide answers about the engine repair services needed. You can now make an informed decision about your vehicle and how to proceed.

In the event an error message doesn't trigger but you're noticing problems with your vehicle's performance, bring it in for a check. Slow-cranking, rough idling, stalling, knocking, or pinging while accelerating are all signs that you may need an engine repair or diagnostic performed.

About Engine Tune Ups

In the past, engine tune-ups were time consuming because they required a motorist or mechanic to check a variety of parts. Engine tune-ups formerly included checking the distributor, cap, rotor, ignition contact points, condensers, carburetors, and more. Today, these parts aren't generally included in engine tune-ups because a vehicle’s electronic control unit controls the engine timing.

Engine Tune Up in Southbury, CT

While not as many parts need to be checked today, engine tune-ups still have a place as part of an engine maintenance plan. There are still parts that contribute to performance that can be checked and replaced as needed to help prevent breakdowns and extend the life of an automobile.

During a tune-up, our service staff will check different parts that have an effect on engine performance, including:

  • Spark plugs: Responsible for igniting the gasoline and air mixture that fuels your engine. A misfiring or damaged spark plug will need to be replaced.
  • Spark plug wires: Transfer voltage created by your spark plug. Old wires can burn out and cause a misfire. 
  • Fuel filter: Help stop debris from reaching your engine. A clogged fuel filter will lead to poor acceleration and poor engine performance.
  • Air filter: Prevents debris from entering the combustion engine. Restricted airflow makes your engine work harder and causes your vehicle to lose horsepower.

The team at Corrigan Motors is ready to provide the automotive service you need with the level of quality you expect. Call or stop by today to schedule your appointment.
