Seafoaming a 2004 and 2008 Pontiac Grand Prix

Travis's Grand Prix always smokes more than mine. One thing i noticed is that every 3800 engine I've done, the smoke is minimal to nonexistent.

Seafoam 2004 Pontiac Grand Prix GTP (supercharged)
Odometer reading at the time of this procedure was just over 88k. On GM's 3800 s/c V6 you DO NOT suck Seafoam through the brake Boost vac hose. SF may damage the Teflon coated s/c rotors. Instead, discount the vacuum line directly beneath he s/c snout. Once you remove the tube/line you'll see a metal fitting going into the engine. Just attach another tube to it so that you can have the running engine drink the SF.

2008 Pontiac Grand Prix Transmission Flutter?
Have a question on my 2008 Pontiac Grand Prix and I want to know if anyone else has had this issue. It seems like the transmission will do this slight "flutter" in between shifts once in a while, mostly at higher speeds or when wanting to kick it into a "passing" gear. Fluid and filter I believe are still factory, so I don't know if that could correct it, or is there another issue? Hopefully not. Saw a video of a Pontiac Grand Am that does the same thing. Any feedback, let me know. Thank you! Grand Am video : http://www.youtube.com/watch?v=4gW4iOl9-8A





How To Seafoam Your Vehicle
2 Can of Seafoam & 1 Can of Deep Creep - 1 can goes into your fuel tank and half of the other one goes into your oil and the other half goes through the brake Booster line. The Deep Creep is sprayed through the throttle body. Let the vehicle sit 15-20 mins. and start up and watch the smoke show. If you have no smoke your vehicle didn't have any carbon build up to clean off.
