Seafoam Instructions
 

I am reading the back of the can right now, and for the Injection part it tells me I can just dump some through the throttle body (1/3) very slowly with the engine on. Then to shut it off for 5 minutes then start it up again. So, does this sound like decent instructions? I was just going to use a funnel maybe and slowly dump it in the TB. My air filter will be off of course, but how much would this choke the car? I will probably have someone giving it gas in case it dies.

thats will choke it alot compare it to shooting carb cleaner in the TB

I just pour it into the gas tank myself. Let the engine do the work

It doesn't clean the intake that way, MOS. I have done that, but the car didn't like running [probably in part to my shitty ignition {before delco conversion} and the fact I needed a tune up something terrible]. You can do that, but try just a little bit at first, and see what happens. If the car doesn't mind running, then go for it. But, don't forget to put some in the PCV valve too, that's a great place.
