How to Remove & Clean Fuel Injectors

The fuel injectors in your engine are a critical component that can dramatically impact your engine performance and fuel efficiency. Over time, the fuel injectors can become dirty, causing inconsistent amounts of fuel to be delivered to each cylinder. Common symptoms of dirty fuel injectors include a rough engine idle, engine power loss and hesitant acceleration. Cleaning your fuel injectors can be accomplished in about 15 minutes with the use of an injector cleaning solution that runs through your fuel system.

Things You'll Need

• Fuel system cleaner
• Plastic funnel

Instructions

1. Open your gas tank's fuel cover and insert the plastic funnel into your fuel filler neck.

2. Pour the fuel injector cleaning solution down the funnel and into your gas tank. Depending on the type of injector cleaner you are using, the amount needed may vary, so check the back of the bottle for specifications on quantity needed.

3. Remove the plastic funnel and reinstall the fuel filler cap.

4. Start your car's engine and allow it to idle for approximately 15 minutes. Additionally, you may go for a short drive to help circulate the injector cleaner through your fuel system.
