I used the cruise control vacuum tube. It is located in the engine bay towards the front on the driver's side. It has a small vacuum line connected to it at a right angle. Make sure the car is good and hot. Keep it running, pull off that vacuum hose and make sure that it is indeed pulling vacuum. Stick it in to the seafoam can or some other container that is holding 8oz(half the can) of the stuff and let it suck it all up. It should take about 30 secs and the nice thing is that because the vacuum hose is so small, it doesn't suck it up too fast which can sometimes stall the engine. After it is all sucked up, turn off the car, reconnect the vacuum hose, and let the car sit for 10 to 20min. Then start it up (might crank over a little longer than usual), watch the smoke show, and go out for an agressive drive (or drive on the highway). Keep driving till it doesn't smoke anymore and enjoy your "new" clean car. Hope this helps.
