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!

Fuel System Services
What Sets Our Approach Apart
Fuel-related issues are often misdiagnosed or overlooked because they don’t always cause immediate breakdowns. Hesitation, rough idling, or sluggish response can slowly become “normal” if no one digs deeper. That’s where Multnomah Automotive stands out. Our technicians take a methodical, data-driven approach, inspecting injectors, fuel lines, pressure regulators, and sensors as a complete system rather than isolated parts. We focus on accuracy before action, using diagnostic insight to determine what truly needs attention and what doesn’t. The goal isn’t just fixing symptoms, it’s restoring proper combustion, protecting engine components, and helping your vehicle perform reliably mile after mile. Clear explanations and thoughtful recommendations are always part of the process, so you stay informed without being overwhelmed.

Subtle Signs Your Fuel System Needs Attention
Fuel system problems rarely announce themselves all at once. They tend to show up quietly, affecting drivability long before a warning light appears. If any of these feel familiar, it’s often a sign that fuel delivery or combustion efficiency is no longer working in sync. Addressing them early can prevent bigger engine issues down the road. Common signs to watch for include:
Rough idling or uneven engine vibration
Rough idling or uneven engine operation can occur when the fuel system delivers an improper air-fuel mixture due to issues such as a clogged fuel injector, weak fuel pump, dirty fuel filter, faulty fuel pressure regulator, or contaminated fuel, all of which can cause inconsistent fuel delivery to the engine cylinders.
Slower acceleration or hesitation when pressing the gas
Hesitation during acceleration can occur when the fuel system cannot supply the correct amount of fuel at the right time, often due to issues such as clogged fuel injectors, a restricted fuel filter, a weak fuel pump, low fuel pressure, or a malfunctioning fuel pressure regulator, which cause a temporary lean condition when the engine demands more power.
Hard starts or longer cranking times
This can happen when the fuel system struggles to build or maintain proper fuel pressure, often caused by a weak fuel pump, leaking fuel injectors, a clogged fuel filter, a faulty fuel pressure regulator, or a failing fuel pump check valve that allows fuel pressure to bleed off after the engine is shut off.
Reduced fuel mileage without a clear reason
Decreased fuel efficiency can occur when the fuel system delivers more fuel than necessary or fails to atomize it properly, often due to issues such as leaking or dirty fuel injectors, excessive fuel pressure from a faulty fuel pressure regulator, a clogged air filter causing a rich mixture, or contaminated fuel that leads to incomplete combustion.

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.
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.
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!
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.
