there is three stages of seafoam.... one is on your gas tank to clean injectors, two is in your oil about 200 miles before you change ur oil to clean carbon buildup and the third in on your vacum near ur brake boster u put in a can of that (they say one third but i put a whole ) slowly without lettint it choke when u have about 1/3 left pour it all to make ur engine choke let it set for about 30 minutes.. turn on your car/truck and let it smoke out.. the more smoke the dirty it was... i have done it twice in my camaro ss and the first time it was alot of smoke the second time was just a little.. i have done it to my 05 yukon too and gas mileage increased about 1.5 mpg.. you can google it.. its good to do...

i worked at place where they did this too with a bottle with an I.V looking thing on it that slowly dripped the cleaner into the TB via the brake booster hose. same result of, the dirtier the system, the more smoke.
i always worried about the CAT's when we did that. it just seems really odd to me.

haha yea.. also forgot thanks peterey02 for reminding me.. deepcreep from seafoam.. you get a bottle of that and spray that into your TB.. i also did the whole can ... its a pain sometimes.. what i did was got my wifes toothbrush ( lol j/p ) and cleaned the TB with the deep creep making sure that carbon didnt go into the intake manifold.. then after the outside was nice and clean sprayed the entire can into the TB so it goes into the manifold..
