Diagnostics
Check Engine Light & Diagnostics in Four Oaks, NC
A warning light, a strange noise, or a problem that only happens sometimes — we test the vehicle to find the real cause instead of guessing at parts.
Custom Auto Repair LLC provides check engine light testing, electrical diagnosis, and complete vehicle health evaluations for drivers in Four Oaks, Benson, Meadow, Blackmans Crossroads, and Johnston County.
What we diagnose
- Check engine, ABS, and other dashboard warning lights
- Rough running, misfires, stalling, and hard starting
- Electrical faults, including intermittent problems
- Starting and charging system issues
- Noises, vibrations, leaks, and drivability complaints
- Complete vehicle health evaluations before a road trip or purchase
Diagnosis, not guesswork
A stored trouble code tells us which system reported a problem — it does not name the failed part. We use the code as a starting point, then test the circuits, sensors, and components involved so the repair fixes the actual fault. That saves you from paying for parts your vehicle never needed.
Complete vehicle health evaluation
Not sure what shape your vehicle is in? We can inspect fluids, tires, brakes, steering and suspension, belts and hoses, battery and charging, lights, and visible leaks, then walk you through what needs attention now and what can safely wait.
Then we give you a plan
After testing, we explain what we found in plain language and provide a repair plan and estimate before any work begins. Repairs are backed by our 3-year/36,000-mile warranty on parts and labor, unless otherwise noted on your invoice.
Frequently Asked Questions
- My check engine light is on. Can I keep driving?
- A steady light usually means you should have it checked soon. A flashing light can indicate a misfire that may damage the catalytic converter, so stop driving and call us.
- Isn't a free code scan enough?
- A trouble code points to a system, not a failed part. Proper diagnosis means testing the circuit or component so you replace the right part the first time.
- What is a complete vehicle health evaluation?
- It is a full look-over of your vehicle — fluids, tires, brakes, steering and suspension, belts and hoses, battery, lights, and visible leaks — so you know what needs attention now and what can wait.
- Do you handle electrical problems?
- Yes. We diagnose and repair electrical issues including starting and charging problems, lighting, power accessories, and intermittent faults.
