Auto Diagnostic FAQs


How do vehicle diagnostic systems work?

OBD stands for On-Board Diagnostics and is a sophisticated computer that collects vital information from a network of sensors, monitoring engine performance, emissions, and other key functions. It not only regulates various car systems but also acts as a diagnostic tool, alerting you to potential problems before they become major issues.

How long does a car diagnostic last?

While a basic diagnostic test typically wraps up in 1-1.5 hours, complex issues demanding further examination and component access/testing can extend the process to 2-3 hours. The length ultimately depends on the severity of the problem and the potential presence of multiple underlying culprits.

What is included in a car diagnostic test?

Diagnostic tests are like X-rays for your vehicle, utilizing specialized equipment to scan its complex systems and components like the engine, transmission, and throttle. From more minor issues to intricate electrical glitches, these tests diagnose a wide range of potential problems. However, interpreting the data they generate requires trained professionals, making dealer shops and skilled mechanics your best bet for accurate diagnoses.

What Our Customers Are Saying

Eddie and the rest of the team took incredible care of me and my vehicle. I wouldn’t trust anyone else to service any of my vehicles! Eddie even went above and beyond by helping me find the right headers and exhaust and assisting me with placing the order. If you’re looking for a trustworthy mechanic who can do just about anything, you’ve found the right place. Anyway, here’s my Vette that they’re building! Super happy with everything so far. :)

I seriously can’t say enough good things about Eddie and Quick Shift Auto. I brought my 2004 Chevy Silverado in with a bunch of issues like reduced engine power, a flashing check engine light, a cylinder misfire, oil leaks, hard starting, and just overall not running the way it should. This truck has a lot of miles on it, so I was honestly starting to wonder if it was just getting to the end of its life. Eddie took the time to actually figure out what was going on instead of just throwing parts at it. They did a full tune-up, checked compression, replaced the plugs and wires, fixed the valve cover leaks, professionally cleaned and flow-tested the fuel injectors, and worked through the misfire issue. He kept me updated throughout the process and was straight with me about what the truck needed. I got it back and I’m not exaggerating when I say it feels like my truck is back to life. It starts right up, I’ve had it on the freeway at 75–80 mph, no check engine light, no reduced engine power, no hesitation, nothing. It honestly runs smoother than I can remember. This Silverado may not be the newest or flashiest truck on the road, but I love this thing, and getting it back running this good means a lot to me. I had honestly forgotten how much I appreciated driving it until I got it back. If you’re dealing with misfires, reduced engine power, check engine lights, rough running, or you’ve got an older truck that other shops make you feel like isn’t worth fixing, go talk to Eddie. He knows what he’s doing and made the whole process feel easy. Huge thank you to Eddie and everyone at Quick Shift Auto. You guys seriously brought my truck back to life. I’ll definitely be coming back here for anything I need in the future. 10/10.
