I just poped off the intake tube, disconnected the maf and sprayed the stuff in while truck idled. I shut it off and let it sit. I also sprayed alittle throught the top pcv inlet.

you can do the cylinder clean with the liquid stuff.
From LS1tech,:
I bought 2 bottles and a plastic squirt bottle.
remove plugs shoot equal amounts in each cylinder, let sit for 3 hours, (anymore I heard it gets too much in oil)
than crank it over for about 15 seconds.
use alot of rags and clean up the mess.
Throw the old plugs back in and run it for a little while, until the smoke stops.
Change the oil and plugs and your back in business.
