Over time, carbon deposits and contaminants can clog fuel injectors, leading to reduced power, poor fuel economy, and rough idling. Regular fuel injection service ensures your engine runs smoothly and efficiently.
At A-Plus Auto Service, our certified technicians use professional-grade cleaning equipment and solutions to restore your fuel injectors to like-new condition. We thoroughly clean the entire fuel system, remove harmful deposits, and test each injector to ensure proper spray pattern and flow rate.

Rough Idle
An engine that shakes or vibrates at idle often has clogged injectors delivering inconsistent fuel amounts to each cylinder.
Hesitation During Acceleration
Stumbling or hesitation when pressing the gas pedal, especially from stops, typically indicates restricted fuel flow through dirty injectors.
Hard Starting Issues

I don’t usually leave Google reviews, but I had such a great experience here. It was really easy to schedule an appointment, everyone was very friendly and took the time to explain everything clearly, and the whole process was quick and smooth. The pricing was also very reasonable. As long as I’m living in South Bend, I’ll definitely come back here if I have any issues with my car. Thank you so much!

Val and the boys at A-Plus Auto Service have been amazing. I brought my car to them as they work with my warranty. I am so glad I picked them out of all the other shops. They explained all my issues and fixed the items promptly. They earned a return customer because of thier customer service skills.

The guys at A-Plus Auto did a great job of communicating what was needed to keep my older car driving safely. Their prices were reasonable and they were able to get some of the repairs covered under warranty. Thanks!
