They are the best!!! They could’ve charged an arm and a leg, but didn’t. They are integral, and good people. I’m a teacher, and we had a hard week at home. Mike’s genuineness, and integrity, were very timely, and appreciated. We will go to the shop again and again.

Jason helped fix multiple issues in my Toyota for $2000 less than what the dealer wanted. Jason and his team worked quickly and communicated clearly about issues that needed to be addressed. As long as Jason is there we’ll be bringing in our cars for service.

Good, honest service. Reasonable prices. Jiffy Lube is right across the street from me, but I still make the 20 minute trip to Multnomah Automotive because of those qualities.

Fuel Injector Cleaning Service

why choose our fuel injector cleaning service?

Contaminants such as dirt, debris, and carbon deposits gradually build up in your vehicle’s fuel injectors, hindering their ability to deliver fuel effectively. This buildup can disrupt the delicate balance of air and fuel in the combustion chamber, leading to incomplete combustion, reduced power, and increased emissions. 

Neglecting to fix these issues can lead to more problems with your engine later on. When fuel injectors are dirty, your car might not work as well and could end up using more fuel. Plus, if you don’t get a fuel injector cleaning service regularly, it could damage other parts of your engine.

Our fuel injector cleaning service utilizes advanced equipment and specialized cleaning solutions to thoroughly remove dirt, carbon deposits, and other contaminants from your fuel injectors.

Signs That It's Time For Fuel Injector Cleaning

This buildup of dirt and gunk can cause issues like carbon buildup on valves and pistons, and it can even make some parts wear out faster. That’s why it’s important to clean your fuel injectors regularly – it keeps your engine working well and can help prevent bigger problems in the future.

 

If you notice a sudden decrease in fuel efficiency, it could indicate that your fuel injectors are clogged or dirty. This can lead to improper fuel delivery and inefficient combustion.

A rough idle or misfiring engine can be a sign of dirty fuel injectors. When injectors are clogged, they may not deliver fuel properly, causing the engine to run unevenly.

 If your vehicle’s onboard diagnostics system detects a problem with the fuel system, it may trigger the check engine light. This could be due to clogged injectors affecting fuel mixture or emissions.

Dirty fuel injectors can lead to higher emissions due to incomplete combustion. If you fail an emissions test or notice black smoke coming from your exhaust, it could indicate injector issues.
