Don't fret if you don't get a good smoke show. That just means that your engine didn't have a ton of gunk built up inside it. It all depends on the area you live in as to what addatives are used in your fuel. Some fuels leave behind more deposits than others.

Also, for skitzobmxr your '91 just has the round air filter assembly (being TBI) but the rest of the list above applies.

 

I dont think the seafoam will be that efficent in the throttle body. Thats what the sea foam deep creep is for. Dump the seafoam cleaner in the brake booster line and use the deepcreep in the throttle body

 

Where do you think it goes through when you pour it into the brake booster line? It all goes to the same place.

*EDIT* now if you want to clean the TB, then I would agree with you, but for a top engine clean, the TB is actually the preferred application method.

 

ya thats wut i wuz saying earlier...couldnt u just pour it in ur gas tank and it would eventually get to the TB

 

Couldnt it puddle inside the intake? When I did it in the brake booster line it turned into a mist with the vaccum. The deep creep is to clean all the crap inside the intake.

 

For your TBI motor, yeah, that will clean you injectors, but it won't be in sufficient enough concentration to clean the carbon from the intake, valves, and cylinders.

 

You do not want to pour it into the TB like you are pouring a glass of milk, but so long as you listen to your engine, you won't pour enough in to cause pooling. The same vacuum is present at the TB as is present at the booster hose. The small opening of the TB will cause the vacuum to do a pretty decent job of atomizing it.

 

Just a thought but seeing as some people are getting confused about this I am sure someone that knows exactly how to do this might want to do this to their truck and make the video. Might answer alot of questions by actually seeing it done. Just a thought.

 

I plan on making a how to on just a general TB seafoam procedure...

 

ya a video woud be amazing it would help me out alot cuz when i read words half the time i dont even understand wut im readin and i have to read it 150 times and i still dont get it
