1,000+ verified reviews Symptoms worth a diagnostic
- A fault that comes and goes
- Intermittent problems have to be caught live — by the time you park, the evidence is gone.
- Rough idle or stumbling
- A misfire from ignition, fuel, or air/fuel metering — live data narrows it quickly.
- Hesitation or lost power
- A sensor, fuel-delivery, or timing fault. Testing beats swapping parts on a hunch.
- Hard starting or stalling
- Could be spark, fuel, or a security/sensor fault — a scan isolates which one.
- Fuel economy dropping
- Often an oxygen sensor or air/fuel fault quietly running the engine rich.
- A new noise under load
- Usually mechanical. We pair live data with hands-on tests, not parts-swapping.

When your engine misfires, idles rough, stalls, or loses power, we find the cause by testing — live sensor data while it runs, fuel and ignition delivery, and compression where it's warranted. Many of these faults never set a warning light, so reading a code alone won't answer them. We fix the root cause, not the symptom, and you know the price before we start.
A modern engine is managed by dozens of sensors and control modules, and when something goes wrong the symptom rarely names the cause. A miss you feel at a stoplight, a hesitation when you merge, a stall that only happens cold — each one can trace back to ignition, fuel delivery, air metering, or compression. Telling those apart is testing work, not guesswork, and that’s what a diagnostic buys you: the real problem found the first time instead of a sequence of parts.
Plenty of these faults never set a light at all. When the computer has logged nothing, the answer comes from live sensor data, fuel and ignition testing, and compression readings rather than a stored code. Kevin Christensen’s GM and Toyota factory training shapes the method here: structured testing that rules things out in order, not guessing and swapping parts on your dime.
On the Space Coast, salt air and humidity are hard on connectors, grounds, and sensors, so corrosion is behind more “mystery” faults than people expect — and it’s exactly the kind of thing a careful diagnostic catches. Whatever yours turns out to be, we’ll tell you what’s wrong, what it costs, and what can safely wait before any work begins. That’s the standard from our ASE-certified, family-owned shop, held since 1998.
A Scan Is Where Diagnosis Starts — Not Where It Ends
A scan tool reads what the computer noticed; the diagnosis is testing which part actually caused it — the difference between replacing one failed sensor and paying for three guesses. We test circuits, sensors, and mechanical causes before recommending work, so a code doesn’t automatically become the biggest part it could name. It’s the testing behind every check engine light visit, and it’s what tells us when a problem is heading toward real engine repair — and when it isn’t.

Frequently Asked Questions
What does a diagnostic scan cost?
A quick scan to pull the trouble code is free. A full diagnostic — tracing that code to its actual cause with live data and component testing — runs $75–$150, and we credit it toward the repair if you go ahead. Either way you know exactly what's wrong before we recommend any work, with no guesswork.
There's no warning light. Do I still need a diagnostic?
Yes — that's the common case for a driveability complaint. Plenty of faults never store a code at all, so a scan finds nothing and the answer has to come from testing: live sensor data while the engine runs, fuel and ignition delivery, and compression where it's warranted. If a warning light is what brought you here, our check engine light service covers that instead.
Can you handle fuel system and transmission issues?
Yes. We diagnose fuel pump failures, injector clogs, transmission codes, and shifting problems. We use specialized equipment and are trained on domestic and import systems. Complex transmission work may require specialist referral, but we guide you through options.
What's an oxygen sensor and why does it fail?
Oxygen sensors monitor exhaust gases and tell the engine computer how to adjust fuel mixture. They fail after 60,000–100,000 miles due to carbon buildup and heat. A bad O2 sensor hurts fuel economy and can damage the catalytic converter. We replace them promptly.
