Engine Diagnostics in Addison, TX
If your vehicle isn’t running like it used to — or a warning light has come on — it’s time to get a professional engine diagnostic. At Eagle Transmission and Auto Care of Addison, TX, we provide advanced computer diagnostics and hands-on inspections to get to the root of any engine-related issue.
Modern engines are controlled by sensors and electronic modules. When something fails, your vehicle stores error codes — but those codes only tell part of the story. Our certified technicians go beyond the basics to determine exactly what’s wrong and what needs to be done.
What Is Engine Diagnostics?
Engine diagnostics is the process of identifying performance issues, sensor failures, or internal damage using both technology and hands-on testing. It typically includes:
- Scanning the onboard computer for error codes (OBD-II)
- Analyzing real-time data from engine sensors
- Performing physical inspections of key components
- Verifying issues through road testing or manual testing
- Confirming the exact cause before recommending repairs
This process helps avoid unnecessary part replacements and gets your vehicle back to proper performance faster.
When You Need an Engine Diagnostic
You should schedule an engine diagnostic if you notice:
- Check engine light is on or flashing
- Rough idling or shaking at stoplights
- Poor fuel economy
- Hesitation or loss of power when accelerating
- Engine stalls, misfires, or won’t start
- Unusual smells or noises under the hood
- Reduced performance or driveability issues
Even if your car is still running, these symptoms can signal early warning signs of serious problems.
Remember, most engine malfunctions can be avoided with regular maintenance.
By taking care of minor engine problems early, you will save a costly engine rebuild somewhere down the road. Auto engine services are a vital part of a driver and his desire to have his car in the best working condition.
It is important to have the engine checked and double checked to ensure that it is good to go.
From routine maintenance to major engine replacement or repair, Eagle Transmission’s Certified Service experts are trained and equipped with the expertise on engine repair and the skills to maintain your vehicle’s optimal performance.

- Reduced throttle response
- Unusual engine sounds
