Reliable Engine Diagnostics & Repair in Columbia, SC

T&G Auto Repair LLC offers professional engine diagnostics and repair services in Columbia, SC using advanced computer diagnostics and over 20 years of hands-on experience to accurately identify and fix engine problems the first time.

Modern engine diagnostics uses professional-grade computer tools to read error codes, monitor sensor data, and identify performance issues in your vehicle's engine system.

When your check engine light comes on or you notice rough idling, poor acceleration, or strange noises, diagnostic testing pinpoints the exact source of the problem. Our technicians use advanced equipment to scan your vehicle's computer, analyze live data, and test individual components.

This approach saves time and money by eliminating guesswork. Instead of replacing parts based on assumptions, we confirm the root cause before recommending any repairs.

High-mileage vehicles frequently experience issues with spark plugs, ignition coils, fuel injectors, oxygen sensors, and mass airflow sensors that affect performance and fuel economy.

Drivers in Columbia often encounter problems related to stop-and-go traffic, which puts extra stress on engine components. Carbon buildup, worn ignition parts, and sensor failures can cause hesitation, stalling, or reduced power.

Other common issues include vacuum leaks, failing catalytic converters, and timing chain wear. Each problem creates specific symptoms that our diagnostic tools help us identify quickly and accurately.

Yes, extreme heat can accelerate wear on engine seals, gaskets, hoses, and cooling components, often revealing underlying problems in older or high-mileage vehicles during summer months.

Columbia's hot, humid climate puts added strain on engines, especially during long commutes on busy highways. Heat causes fluids to break down faster and can expose weaknesses in cooling systems, belts, and rubber components.

Vehicles driven daily in warm weather benefit from regular diagnostics to catch small issues before they escalate into costly repairs. Addressing minor leaks, worn hoses, or aging sensors early helps maintain performance and prevents breakdowns during peak heat.

Our technicians explain diagnostic findings clearly, provide honest recommendations, and outline repair options so you can make informed decisions about your vehicle's care and budget.

We believe in transparent communication. After completing diagnostics, we walk you through what we found, why the issue matters, and what it will take to fix it right. You'll never face surprise charges or unnecessary upsells.

Many engine repairs improve fuel efficiency, restore power, and extend the life of your vehicle. Whether you need a minor sensor replacement or a more complex repair, our team uses quality parts and proven techniques to deliver reliable, long-lasting results.
