It should look something like this, you can pour the Seafoam into the funnel slowly 1/3 of the can your engine should choke and cut off you'll also see smoke coming out of ur exhast, once you finish pouring the SF into the intake let your car set for 5mins then start your car and go for a ride WOT.

start your engine and step on the gas a little

POOF a shit load of smoke will come out

Time for you to get in to your car and go WOT around the block maybe even a trip on the freeway.

Do this a couple of times
