just bought the "sea foam" today at pep boys but i had STP throttle body&intake cleaner today i just took off the intake hose then just sprayed to the throttle body its soooo dirty. now is shining... didnt have chance to go now... now its like 5 inch snow on the ground... ill see tomorrow if theres any change!
i tried the throttle body spray cleaner thing too. but the result of sea foam is more amazing. try to find a intake hose that sucks in, put the hose in the sea foam bottle and let it suck up 2/3 of the liquid. shut off the car and let it sit for 5 minutes. turn it back on and start rev the hell out of it till u see no more smoke.
