Check Engine Light & Engine Diagnostics, Right in Your Driveway

It depends on your vehicle and the problem. A loose gas cap, a failed sensor, a misfire and an intermittent electrical fault take different amounts of testing to track down. Diagnostic testing is a separate charge from the repair itself. Once we find the cause, you get an upfront estimate for the repair, and no work begins until you approve it. There are no hidden fees. Because we don't pay rent on a traditional shop, our overhead is lower and those savings are passed on to you. Call or text 937-609-3554 with your year, make and model and what the car is doing to get on the schedule.

Yes. We are a mobile mechanic, so we run engine diagnostics right in your driveway, apartment lot or workplace parking lot. All we need is a safe spot to park next to your vehicle. That means no tow and no driving a car that's running poorly to a shop. Many of the repairs we find can be done during the same visit. Larger engine repairs are done at our offsite repair facility, and we pick up and deliver your vehicle.

The check engine light means the engine computer has detected a problem with the engine, the ignition, the fuel system or the emissions system and stored a trouble code. The cause can be as small as a loose gas cap or as serious as a misfire that's damaging the catalytic converter. The light alone doesn't tell you which, so it's worth having it diagnosed.

A steady light means a fault has been detected and should be checked soon. A flashing light usually means a severe misfire is happening right now, sending unburned fuel into the exhaust where it can overheat and ruin the catalytic converter. If your light is flashing, reduce your speed, avoid hard acceleration and call us. Since we come to you, you don't have to keep driving it.

If the light is steady and the car drives normally, it's usually okay to drive for a short time, but have it checked soon. Small problems like a failing sensor can hurt fuel economy and lead to bigger repairs. If the light is flashing, the engine is overheating, you smell fuel, or the car is losing power, stop driving and call us.

A code reader tells you which system reported a problem, not which part failed. A code for a lean condition, for example, can come from a vacuum leak, a dirty airflow sensor, a weak fuel pump or a leaking injector. Replacing parts based on the code alone often means paying for parts you didn't need while the real problem stays. We use the code as the starting point, then look at live data and test the components to confirm the cause.

No. Clearing the code turns the light off, but the fault that set it is still there, and the light will come back once the computer detects it again. Clearing codes also erases the freeze-frame data that helps pinpoint the problem, and it resets the readiness monitors needed to pass an emissions test. It's better to leave the code stored until the car is diagnosed.

Yes. The fuel system is sealed to keep fuel vapors in, and the computer tests that seal. A loose, worn or missing gas cap can set an evaporative emissions leak code. Tighten the cap until it clicks and the light may go off after several drive cycles. If it doesn't, the leak is somewhere else in the system and needs to be diagnosed.

The most common causes are worn spark plugs, a failing ignition coil, a clogged or leaking fuel injector and vacuum leaks. Less often, a misfire comes from low compression or a mechanical problem inside the engine. You'll usually feel a misfire as a rough idle, shaking, hesitation or loss of power. We test the ignition, fuel and air side to find which cylinder is misfiring and why.

Yes. A car that cranks but won't start usually has a fuel, spark or sensor problem, while one that won't crank at all usually has a battery, starter or electrical problem. Since we come to you, a no-start doesn't need a tow to get diagnosed. We test the system that's failing and tell you what it takes to get the car running again.

Yes. Intermittent problems like occasional stalling, a light that comes and goes or a hesitation that only happens when the engine is warm take more work to catch. Stored codes and freeze-frame data show the conditions when the fault happened, and we test under those conditions when we can. Telling us exactly when it happens, cold or warm, at idle or at speed, helps a lot.

Yes. We diagnose battery drains, charging problems, wiring faults and dashboard warning lights, along with the check engine light. If a battery keeps dying or a warning light won't go off, we find out whether the problem is the battery, the alternator, a wiring fault or a module that won't shut off.

Many problems are found during the visit. Intermittent faults, electrical problems and issues that need more testing can take longer. If the repair can be done on site, we can often do it during the same visit once you approve the estimate. Larger engine repairs are done at our offsite repair facility, with pickup and delivery. Either way, we tell you upfront.

Yes. Once we find the cause, we explain it in plain English and give you an upfront estimate for the repair. Many repairs, like sensors, ignition coils, spark plugs and gas caps, can be done during the same visit. You decide whether to go ahead, and no work begins until you approve the estimate.

In most areas that require emissions testing, a check engine light that is on is an automatic failure. Recently cleared codes can also cause a failure because the readiness monitors haven't finished running. We diagnose and repair the fault so the light stays off and the car is ready for the test.
