Engine Repair & Diagnostics in Alpharetta, GA
When your vehicle isn’t running the way it should, the signs are often clear. Maybe the check engine light flickers on during your commute, you hear knocking under the hood, or your car just doesn’t accelerate the way it used to. At Speed Auto Repair, we specialize in Engine Repair & Diagnostics in Alpharetta, GA, that take the guesswork out of what’s happening with your vehicle. With advanced car diagnostics, skilled technicians, and a commitment to keeping your vehicle dependable, we make engine care stress-free.
Why Engine Diagnostics Matter
Modern car engines, controlled by ECUs, use sensors to detect deviations and send diagnostic trouble codes (DTCs), triggering the check engine light. This warning can signify a minor issue, such as a loose gas cap, or a major problem, like a failing catalytic converter or engine damage. Ignoring it leads to further damage, reduced fuel efficiency, and increased emissions.
At Speed Auto Repair, we use professional diagnostic tools beyond generic code readers. Our advanced equipment interprets manufacturer codes, views live sensor data, performs bidirectional control tests, and conducts comprehensive system analyses. This allows our certified technicians to pinpoint the exact root cause, avoiding guesswork and unnecessary part replacements. Our goal is to get you back on the road safely and efficiently, with correct diagnoses and repairs.

The Difference at Speed Auto Repair
Plenty of shops offer engine repairs, but not all take the same detailed approach. At Speed Auto Repair, we focus on accuracy and clear communication. Instead of swapping parts until something works, we rely on precise car diagnostic testing and years of hands-on experience to find the real issue. That means fewer surprises, more reliable fixes, and peace of mind every time you drive away.
Engine Rebuilds and Engine Swaps
Sometimes, an engine is too damaged for simple fixes. When that happens, we can perform complete rebuilds or even an engine swap. Rebuilding involves replacing worn or damaged parts inside your current engine to restore it. An engine swap, on the other hand, involves installing a replacement engine to bring new life to your vehicle.
These services are especially useful for drivers who love their cars but face major engine damage. Instead of replacing the entire vehicle, a rebuild or swap can keep your car on the road for years to come.
Engine Diagnostics in Everyday Driving
Even if your car seems fine, periodic engine diagnostics can catch issues before you notice them. Many drivers are surprised to learn that their vehicle was storing error codes without turning on the check engine light. Running car diagnostic testing during routine visits helps us find and address small issues early, ensuring your car runs as efficiently as possible.
Preventive Care for Engine Longevity
Routine care is the best way to avoid expensive engine repairs. Our preventive services include:
- Regular oil changes with the right type for your engine
- Fluid level checks (coolant, transmission, power steering)
- Spark plug and ignition system inspections
- Air and fuel filter replacements
- Cooling system flushes and inspections
- Periodic car diagnostics to spot hidden issues
By staying ahead of maintenance, you’ll avoid unexpected breakdowns and keep your car performing at its best.
Car Diagnostics: Beyond the Check Engine Light
The check engine light gets most of the attention, but diagnostics aren’t limited to that warning. Our testing also helps with:
- Identifying emissions problems that impact inspections
- Tracking down misfires and poor fuel efficiency
- Finding electrical issues tied to the engine
- Verifying that repairs were successful after installation
This thorough process ensures we don’t just fix the symptom but solve the actual problem.
Common Alpharetta Engine Concerns

- Overheating in summer traffic due to the cooling system strain
- Oil leaks from worn gaskets on high-mileage vehicles
- Check engine lights tied to emissions or sensor failures
- Timing chain wear in vehicles with heavy daily use
Our team is familiar with these problems and has the expertise to get you back on the road quickly.
