I recently searched like crazy and decided to use some sea foam through my vacuum line. I only used a little, maybe 1/3 of a can. After, it smoked for a min. and that was it. Well, the prob. I had was before I did it, when I would restart it warm, it would sound like it wanted to die a little then it would start all the way up. Since I used the sea foam, this problem has seemed to get a little worse. Does anyone know what this could be?
