A Clean Sweep (Fuel Injector Cleaning)

Your vehicle gets its power from burning fuel, usually gasoline, and it counts on something called fuel injectors to send gas to the engine in a spray that is easy to ignite. It’s a precise operation, and when it’s working well, you have plenty of power and an efficient engine.


But after time, contaminants in the fuel system may prevent the injectors from spraying like they’re supposed to. They can also shoot contaminants into the engine. 


One sign that could point to dirty fuel injectors is a misfiring engine. Misfires can be caused by several things, so it’s a good idea to bring your vehicle to us so we can trace the cause. Another sign is that your fuel economy has gone downhill or your engine doesn’t have the “pep” it used to.


If we discover that your injectors are clogged or not working the way they should, we can clean them to get rid of those contaminants to restore your engine to its top performance. When you bring your vehicle to us, we will connect the flushing equipment, flush out the injectors and reassemble the system.


A good time to have fuel injectors inspected is when you bring your vehicle in for routine maintenance. An oil change is an ideal time to have a technician take a close look at your entire fuel delivery system. 


When you have your fuel injectors cleaned, you may see your mileage go up, your engine performance improve, and your exhaust emissions decrease.

If there’s one thing you should pay attention to with your vehicle, it’s the temperature gauge. It’s the one that may say C---H (that means “cold---hot”).

Most San Diego drivers are too young to remember life before power steering - cranking those great big steering wheels! It was a pretty good workout. Now power steering is standard. Let's look at how it works.
