Engine Diagnostics Services in Groton, CT

Understand What Your Engine Is Telling You

Your car’s engine works hard every day, and when something isn’t quite right, it usually tries to give you a heads-up. Maybe the check engine light pops on. Maybe the engine sounds different or doesn’t run as smoothly as usual. Whatever the case, the team at Antonino Acura in Groton, CT is here to help figure out what’s going on. Our engine diagnostics service takes the guesswork out of the equation so we can help you get back on the road with confidence.

What Happens During an Engine Diagnostic?

Today’s vehicles rely on onboard computers and sensors to keep everything running properly. When something’s off, those systems generate error codes—kind of like the car’s way of saying, “Hey, something’s not working right.”

When you bring your vehicle to us, our trained technicians use advanced diagnostic tools to scan for those codes and uncover any underlying issues. We’ll check for problems in key systems like:

• Ignition and spark
• Fuel delivery
• Emissions and exhaust
• Engine sensors
• Transmission and drivetrain

Once we have the data, we’ll walk you through what we find and help you decide on the next steps. No pressure—just straightforward answers.

Why Choose Antonino Acura?

There’s a big difference between just reading an error code and truly diagnosing a problem. At Antonino Acura, we go beyond the basics. Our technicians have the experience, equipment, and manufacturer-specific knowledge to accurately identify what’s happening under the hood.

We don’t believe in quick guesses or temporary fixes. We’ll give you the facts, explain your options, and let you make an informed decision about any needed repairs.

Signs You Might Need a Diagnostic Check

Not sure if it’s time to have your engine checked out? Look for any of these warning signs:

• The check engine light is on or blinking
• The engine is running rough or stalling
• Strange sounds coming from under the hood
• Your gas mileage has suddenly dropped
• The car is slow to start or won’t start at all

Even if your vehicle still feels okay to drive, a quick diagnostic scan can uncover hidden issues before they become major problems.
