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.

I had a great experience getting my Honda Fit 30,000 mile service and new tires. Communication was quick and clear, staff were friendly, and I felt the cost was reasonable. Thanks for making this normally stressful process very easy!
I was in need of repair and this business was quick, customer service polite, and they got the repair done sooner than they anticipated. Also, they followed up personally which was really nice.
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!
Great service, quick, great price and helped us through the issues we were having with our car. Called to give us updates too.
Master Tech in Gresham did a nice job on the mechanical repairs and maintenance items. If there is ever an issue or concern, they will make it right. The service is always courteous and professional.
Had them do a routine service on my transmission and the work was done in a timely matter and Daren and the other employees were polite and helpful.
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!
I was able to schedule regular maintenance on short notice. The diagnostic showed a couple of things that needed immediate attention , which they were able to complete on the same visit. My 2001 Honda is running better now than it has in years!
MasterTech is so different than other mechanics! They give you updates with photos via text about what should be repaired or needing any kind of attention in the future. Also, their warranty is longer than most plus the FREE ROADSIDE ASSISTANCE is just as good as AAA without the fee. I’d recommend MasterTech to anyone. Getting an appointment is easy to do
Fast service and quick to find and repair issue. Staff polite and knowledgeable. Explained options and got my vehicle back to me quickly.
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.
The employees were very nice and provided all the information I needed and gave accurate estimates and completed all tasks in a timely manner. However they are a little more on the spendy side.
