heh, I did it on my old 2001 Chevy Prizm when I was told I had carbon buildup and the mechanic wanted >$200 to clean it.I hooked an extension tube onto a vac hose (past the MAF sensor). Sucked 1/3 can sea foam, and about 2 cups of hot water, SLOWLY. went out and drove it like I stole it, then repeat...
