What does an engine diagnostic test do?

An engine diagnostic test uses advanced computer scanning tools to read error codes, check sensors, and identify performance issues. It helps pinpoint problems like misfires, sensor failures, or fuel system issues.

When should I get an engine diagnostic?

If your check engine light is on, your vehicle is stalling, running rough, losing power, or getting poor fuel economy, it’s time for a diagnostic test.

How long does an engine diagnostic take?

Most diagnostic tests can be completed in 30–60 minutes, depending on the issue and the depth of testing required.

What happens if my check engine light is flashing?

A flashing check engine light usually signals a serious problem like a misfire or fuel system issue. You should stop driving and have your vehicle inspected immediately to avoid major engine damage.

Can engine diagnostics find all problems?

Diagnostics reveal error codes and system data, but some issues may also require a visual inspection, performance testing, or additional troubleshooting.

When is an engine replacement necessary?

An engine replacement is usually recommended if your engine has severe internal damage, cracked blocks, blown head gaskets, or repeated major failures that make repairs more costly than replacement.

How long does an engine replacement take?

Depending on your vehicle, an engine replacement can take a few days to over a week. This allows time for removal, installation, and thorough testing to ensure reliability.

Are used or rebuilt engines reliable?

Yes, when installed correctly. At CARS, we use high-quality used, rebuilt, or new engines and back our work with professional installation and testing.

Is it better to repair or replace my engine?

It depends on the severity of the damage, cost of parts, and your vehicle’s age. Our technicians provide honest recommendations to help you make the best decision for your budget and vehicle.
