Our technicians don’t just plug in a scanner and call it a day; they listen to your concerns, study the symptoms, compare data, and dig into the full picture of your vehicle’s performance. Every test, reading, and visual check is done with purpose, giving you clear guidance about what’s happening and what needs to be done next. We blend technical expertise with human-level clarity so you walk away informed, prepared, and never pressured.

How to Know Your Car Needs a Diagnostic Check
Sometimes your vehicle speaks in subtle clues before anything major goes wrong. A proper Engine Diagnostics appointment helps catch those early signs and prevent something small from becoming a budget-breaking headache. Whether it’s performance changes or warning lights you can’t decipher, an inspection brings everything into focus. Common signs to watch for:
Sudden dips in power
Reasons for this may be 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 intermittent faults detected by the engine control module that trigger temporary limp-mode or timing/air-fuel adjustments.
The dashboard light that keeps reappearing
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.
Strange sounds or shaking
Strange sounds or shaking from the engine can result from problems such as engine misfires due to faulty spark plugs or ignition coils, worn engine or transmission mounts causing excessive vibration, a failing serpentine belt or pulley producing unusual noises, vacuum leaks affecting engine balance, or internal issues like worn bearings or timing components.
Fuel efficiency dropping without explanation
This can be caused by issues such as a clogged air filter restricting airflow, failing oxygen sensors causing an incorrect air-fuel mixture, dirty or leaking fuel injectors, low tire pressure increasing engine load, a malfunctioning mass airflow sensor, or a thermostat stuck open preventing the engine from reaching optimal operating temperature.

The only place I will take my Mustang
Got me on same day and gave me detailed info on diagnosis
Recently had a clutch kit installed on my 05 mustang GT. The guys at Art of Maintenance were knowledgeable, friendly and very communicative. They stand by the work they do, was very impressed with the shop professionalism as well as the customer service.
Very straight forward shop and great value for your money. They fixed my belts and uncovered the issue promptly with one of the bearing being out. I would highly recommend this shop.
I found this place googling around after the soonest appointment I could make at the Ford dealer I’d have gone to had it’s EARLIEST appointment 15 days from when I called. The Art of Maintenance for me in the next morning after a late afternoon call. The car diagnosis was made in a couple of hours post drop off, and, but for a part needing to be brought in the next day, it’d have been done that day. As it was, brought it back the next morning, and the car was done by noon.
The price seemed reasonable to me comparative to any other maintenance I’ve had done over the years, and the staff seemed totally transparent about the issues and the costs, starting by attempting the least expensive fixes first (which worked! phew!). More importantly, they were just friendly and welcoming to this boy who knows nothing about cars.
Will def use them again; although I sure hope to not have to 🙂 (come on, car, get to 300k miles and past this chip shortage BS!!!)
Been taking my car here for a few years for oil changes, etc., and it’s always gone well. Noticed one of my tires was dangerously low on air today and drove it straight there. Even though it was almost closing time, the folks at Art of Maintenance pulled my car into the garage and thoroughly checked and fixed my tires. I really appreciated their quick service to make sure my car was safe to drive.
Fastest oil change I’ve ever gotten. Will keep coming back. Recommend Carl or Mike for the job. Kevin is polite and helpful with questions.
Great mechanic! Very honest and prompt.
So glad to have finally found somewhere to take care of my vehicle! Extremely transparent, excellent work, and best customer service I have ever experienced. I will take my car here as long as I Live in Portland!
Brought my car in needing some major repairs and they were able to help me out right away. They’ve been nothing but efficient and helpful making this process so much easier than I expected!
I had to end up having a lot of work done on my car. They were very good at explaining everything and even showing me old parts they replaced to explain!
Knowledgeable mechanics, skilled communicators.
