Check Engine Light Diagnosis in Arlington & Annandale, VA

Get it checked soon if

• The check engine light is flashing (pull over and call us)
• The engine runs rough, hesitates or stalls
• Fuel economy suddenly dropped
• You smell fuel or see smoke
• Your Virginia emissions inspection is coming up

How we diagnose it

• Scan all modules and record freeze-frame data
• Check for manufacturer service bulletins on your model
• Test the actual part or circuit: sensors, wiring, vacuum leaks, fuel and ignition
• Explain the root cause in plain language
• Written estimate before any repair

Why not just replace the part the code names?

Because the code often points to a symptom. An oxygen-sensor code can be a vacuum leak. A misfire code can be a coil, a plug, an injector or a wiring fault. Testing first costs less than guessing twice.
