just praying now
Normal practice is to put about 1/3 of a can of seafoam into the engine very slowly while the engine is running. Putting it in somewhere near the throttle body is highly suggested and drizzling it in slowly is the safest way. After it is in then you turn the truck off for an hour or so to let it soak and then start it up and burn the residue out. Many people have done it with great success. The remaining 2/3 of a can will go into the fuel tank. Some like to pour a can into the crankcase and run at idle speed until up to temp and then drain the oil, kind of like an enima for the crankcase to flush out the nasty deposits.

That just shows you that I dont pay attention to bs like that, dont get me wrong im not ragging on you at all. It just didnt make sense to do that, to me. im sorry but it said to hook the can to the booster vacuum and suck it out like a Hi-c juice box??? Wow, i would have never guessed. But I hope that nothing serious is wrong with your motor dude. I feel for you. good luck.
