85 p/u 4x4 efi sr5. dont know where to start. got seafoam, and i am trying to put it in, but i dont know how, so what is the method of pouring it in thru the throttle body, without killing the engine?

Thanks

It's the huge vacuum hose that leads from the master cylinder to the engine. Unhook the hose from the engine and feed it through that way. Don't let it suck up too much of the Seafoam or it will stall it out. The best thing to do is to pour the SF into a cup or container and let it slowly suck it up that way. Let us all know how it turns out!

yeah, i put in my moms measuring cup ,and poured it through the pcv valve hose. Thanks next time i am going to pour it through the brake booster line.
