Some Of The Automotive Maintenance, Repairs & Services We Offer

At K & M Auto Services, we do auto repair the way it is meant to be done, with honesty and integrity. We own several auto repair centers located throughout Portland, and our team of professional mechanics is trained to repair any foreign or domestic vehicle model. So, no matter what vehicle you drive, you can rest assured that it is in good hands at K & M Auto. From repairing transmissions to performing routine, scheduled maintenance, we are equipped to handle any vehicle issue.

Vehicles used to rely on carburetors to supply the fuel necessary for combustion, but not too long ago the carburetor was replaced with the fuel injector. Fuel injectors improve your vehicle’s fuel efficiency, make your engine run smoother and reduce the amount of harmful emissions produced when you drive. A fuel injector provides a precisely calculated mixture of gasoline and oxygen to your engine. Even with oxygen levels fluctuating wildly, a fuel injector can quickly supply your engine with just the right amount of gasoline that it needs for combustion. There is a lot of heat generated in the engine, and over time carbon residue can build up on your fuel injector nozzles. This residue can interfere with its performance and diminish the fuel efficiency and performance of your vehicle. Rusty gas lines and nozzles can also result in clogged or inefficient fuel injectors. There are a lot of small, moving parts in a fuel injection system, as well as electrical components. If these parts are damaged or not maintained, then your engine’s performance and fuel efficiency will suffer.

At K & M Auto Services, our hardworking mechanics can repair or clean any fuel injection system. We will eliminate any rust on your nozzles or fuel lines, and we will make sure there are no leaks in your system. If it is a problem with your fuel injector’s electronic components, we can take care of that, too. If you have noticed your engine misfiring, a drop in your car’s fuel efficiency, or other signs of poor engine performance, it could be a sign that your fuel injector is dirty, clogged or leaking. If your car is exhibiting these symptoms, bring it to one of our auto repair centers in Portland and we will get it back to normal promptly and professionally.

With a K & M Auto Services oil change, or any other service, you’ll receive a Touch® Courtesy Check. We’ll look inside, outside, under the hood and underneath the car, then explain the findings and give you a written report. While you’re there, let us perform a Touch® Courtesy Check, which includes a visual check of the following items:

  • Engine air filter
  • Brake fluid
  • Power steering fluid
  • Automatic transmission fluid
  • Coolant/antifreeze
  • We’ll also walk you through your vehicle manufacturer’s recommendations for replacing these vital fluids and filters.
