Once again, how did you test for vacuum leaks? Give me detailed instructions on what you did, step by step. Also what was the results with the seafoam?

i just did it by feel, not sure if I checked all of them. I just did the seafoam today and there was absolutely no smoke coming out of the exhaust. I wonder if I did it wrong. Anyways I drove to Orlando from Tampa, about 1 hour. on the way there the car was sputtering then it stop doing it and on the way back it didnt do it at all. is very strange. I guess i better check the vacuum lines again, im not 100% sure where all of them are. any more suggestions? thanks

Well, I guess the seafoam did it. It hasn't sputter in a week. Keeping my fingers crossed.
Thanks all.

You can also pour it in to your gas and clean you fuel system, injectors, lines, remove any water, etc.
