I've heard of a product that connects to the fuel rail and forces a refrigerant through your injectors and supposedly is one of the best ways to clean your injectors, but never heard the name of the product/adapter kit. Any one know of the product and where to purchase it?
The last time I ran that stuff, I got it from Firestone. I don't remember what it was called though. You disconnect the fuel line and run this stuff like an I.V. bag into the fuel system. It does a good job of cleaning everything it touches.
