Engine Diagnostics
A detailed inspection of your engine systems to catch problems early and ensure your vehicle runs smoothly in every situation.
Master Tech did the brakes on my BMW, they also checked over the full car, and advised with photos what else is recommended. They did a great job and also were able to show me the older brakes. I highly recommend them for any maintenance or repairs!

How to Know Your Engine Needs a Diagnostic
Engines rarely fail overnight, they usually give subtle signals first. Recognizing these signs early can prevent a breakdown and extend your vehicle’s life. With a proper Engine Diagnostics check, you catch problems while they’re still manageable, instead of dealing with surprises on the road.
Signs to schedule a check:
Reduced power or sluggish acceleration
Some reasons for this are a failing fuel pump causing inconsistent fuel delivery, clogged fuel injectors restricting proper combustion, a malfunctioning mass airflow sensor sending incorrect air-intake data to the ECU, ignition coil misfires, turbocharger boost leaks, or faults detected by the engine control module that trigger temporary limp-mode.
Persistent dashboard warning lights
Common reasons for these issues are persistent fault codes stored in the ECU, a failing sensor (like an oxygen sensor or mass airflow sensor) sending intermittent signals, loose or corroded electrical connections, low fluid levels that temporarily trigger alerts, or a problem that was reset but not fully repaired during diagnostics.
Engine noises that sound unusual or rough
Most of these issues are caused by worn valve lifters or timing components creating ticking sounds, loose or damaged heat shields rattling, detonation or “engine knocking” from improper air-fuel mixture or low-octane fuel, failing bearings within the engine, or accessory components like the alternator or water pump beginning to wear out.
Hesitation or stalling during starts
This can be caused by issues such as worn spark plugs or ignition coils leading to misfires, a dirty throttle body restricting airflow, vacuum leaks disrupting the air-fuel mixture, failing fuel injectors delivering inconsistent fuel, or a malfunctioning sensor (like the mass airflow or coolant temperature sensor) sending incorrect data to the engine control unit.

The work was done quickly, cleanly, on time and my truck was all the better for the service they provided. All I could ask for and a little bit more. Highly recommended.
They have a great system of photo documenting what they find during their inspection, and allowing you to access it online. Makes for simple ‘menu’ style of what should/could be repaired or replaced. They also work very quickly.
5 star. They arranged for me a Lyft ride back and forth. Also did a five star inspection on the vehicle. I’ve been using them for a couple of years now. I would highly recommend!
Master Tech provides top-notch service, this time checking my oil and a concern I had with a fuel smell. They are quick, efficient, honest, and great at communicating every step of the way. Thank you!

Great service, quick, great price and helped us through the issues we were having with our car. Called to give us updates too.
Excellent Customer Service, Good Pricing, Great Transparency On Work To Be Done. Especially like that they text you the work order and allow you to review pricing and approve the work you want done. Customer for life!

Very helpful and nice, quick service and easy way to accept or decline which services are offered, will definitely be coming back next time i got car trouble
The technicians at master tech were very helpful with finding the problem with my truck and giving me multiple options in order to fix it. The repairs they did were fantastic, they look and preform perfectly.
A little pricey but worth it. Good communication for the most part. Excellent vehicle inspections with pictures and accurate descriptions. Fast turnaround times unless you are stuck waiting on parts.
