So i just did the seafoam treatment on my 07 v6 and it runs beautifully now...not that it was bad before but perfect and smooth now. I checked youtube and noticed only one video on how to use seafoam on a v6 for the s197 and they didn't exactly do it correctly so i decided to do my own walk through for all you frustrated v6 owners. You can check the video here:

This is how i did it and got great results...remember every person/mechanic will have a different solution to a problem. So if you did your treatment differently then good for you =). if you want i can post my instructions here as well but everything is explained in the video and video description...its my first video so i do a lot of "umms" and pauses haha so just bear with me. Good luck.

If you guys have any suggestions...i'm completely open to any and if needed i would gladly redo the video as long as its helpful for everyone else.
