i have seen before and after pics of auto-rx. has anyone ever seen what seafoam really does? a lot of people think smoke = cleaning not realizing that the product itself is causing the smoke. i doubted it myself but figured i would give it a go anyhow. noticed no difference. now pulling off my throttle body, IAC Valve and EGR tubeand cleaning them thoroughly made a difference. anyone have before/after pics? or a link? and i mean seafoam in the intake, not the crankcase.
