Engine Diagnostics & Repair
FaiRepair's certified Irving technicians use factory-grade diagnostics to find the exact issue fast — no guesswork, no unnecessary parts.
Why Computerized Diagnostics are Crucial
Modern vehicles are controlled by complex engine management units (ECUs). When a check engine light illuminates, it indicates that a sensor has registered a reading outside of factory parameters. Computerized scanner diagnosis reads the exact fault code, providing our technicians with a targeted starting point.
Ignoring persistent engine performance issues can cause severe long-term damage, such as ruining catalytic converters or leading to complete internal engine failure. Our ASE-certified mechanics inspect sensors, fuel lines, spark plugs, and compression to fix the root cause.
What is Included in Our Engine Check-Up
Common Engine Warning Signs
Check Engine Light On
An active warning light means the vehicle computer has detected an electrical or mechanical fault.
Rough Idle or Stumbling
Engine shakes or hesitates during acceleration, often caused by spark plug or fuel delivery issues.
Reduced Engine Power
Sluggish performance or poor throttle response due to sensors failing or clogged exhaust.
Poor Gas Mileage
A sudden drop in fuel efficiency usually points to failing oxygen sensors or catalytic converters.
