I have used seafoam in the intake prior to smog checks for years with good results. I recommend Marvel Mystery Oil as an oil additive.
Seafoam Anyone ?

I did it a few days ago. Very little smoke and my truck is running smoother so far. She was idling rough and running rich. After clearing the code and 34 miles later she is ok. Only time will tell.

Am running a bottle in the tank right now. I used a fuel system cleaner first, with excellent results. It made so much of a difference I decided to do a can of Seafoam two tanks later. I am not seeing the same level of improvement but improvement nonetheless.
I don't think seafoam (via the gas tank) can hurt anything. I am not brave enough nor require it fed directly into the engine via an intake hose somewhere... yet. But when I do, Seafoam it will be!

I searched and searched the forum looking for an answer to my question before posting this, so don't hate me too much for beating this dead horse but how much seafoam do I "slowly add" to the brake booster line?
I bought a 16 oz can and put 8oz in the gas (we were just under 1/4 tank) so I have 8 oz left. I am replacing the spark plugs this weekend and will be doing the seafoam as part of the process. None of the video's, comments or anything said how much to add.
Can I just slowly pour the remaining 8 oz into the vacuum tube or do I need more or less? Any input is appreciated. Thanks

you can do that amount...I used 1/3 of the can when I did it to my truck
When I did my plugs, I did 1/2 can twice through the brake booster, and a full can in the tank. After the first half, I took it out & drover it like I stole it. Then, the night before I did the plugs, I did the remaining half in the booster line. At the end of the pour I allowed it to stall out. Doing it this way left things a little wet with the seafoam. I attribute this to why none of plugs broke 
. That and I used an impact gun.
