To clean fuel injectors, there are two main methods: using fuel additives or performing a more thorough cleaning with a fuel injector cleaning kit. 1. Cleaning with Fuel Additives (Simple Method):

• Start with a nearly empty fuel tank.
• Pour the recommended amount of fuel injector cleaner additive into the fuel tank (popular brands include Redline SI-1 and Seafoam).
• Fill the tank with fuel, preferably Top Tier gasoline.
• Start the engine and let it run so the cleaner can flow through the injectors.
• Repeat this process every oil change for maintenance and to prevent clogging

2. Cleaning with a Fuel Injector Cleaning Kit (More Invasive Method):

• Gather necessary tools: fuel injector cleaning kit, fuel injector cleaner solution, wrench/socket set, air compressor, gloves, and safety glasses.
• Depressurize the fuel system by disconnecting the fuel pump relay and running the engine until it dies.
• Unscrew the canister lid of the cleaning kit and fill it with the recommended cleaner.
• Hang the canister under the hood.
• Attach the kit’s hose to the fuel rail test port (consult your vehicle’s manual for location).
• Connect the air compressor to the canister and adjust pressure to just below normal fuel rail pressure.
• Start the engine and let it run until the cleaning solution is fully used (about 10 minutes).
• Turn off the engine, disconnect the hoses, and reconnect the fuel pump relay.
• Start the engine again to complete the process

Additional DIY Cleaning (Injector Removed):

• Remove the fuel injectors carefully.
• Soak them in a commercial injector cleaning solution.
• Use a brush to scrub off stubborn carbon deposits.
• Some DIY methods involve using carburetor or brake cleaner sprayed through the injector while activating the injector solenoid with a battery to flush out debris

Precautions:

• Always check and replace air and fuel filters before cleaning injectors, as clogged filters can cause similar symptoms.
• Wear safety gear when handling chemicals and pressurized equipment.
• Follow all instructions on cleaning products and kits carefully to avoid damage

This approach ensures your fuel injectors are cleaned effectively, restoring proper fuel flow and engine performance.
