All right thanks again! And according to the can only use 1/3 of the bottle right? The reason i am doing this is because the guy i bought the car from drove it without an air filter for about a month so im hoping the sea foam will clear out any junk in the upper part of the motor. I also am going to run it in my fuel tank to clean injectors ect. because on start up and 4th gear at low rpm if you mash the throttle it kind of feels like its missing on a cylinder but not fully missing (if that makes sense) but runs fine at high rpm.??The brake booster hose is your best bet, as it's the biggest vacuum hose and will allow you to stick a small funnel in it's end to make pouring in the sea foam easier.
