what i found that works best is (some hate me for this) take you intake off and SLOWLY pour it down the TB. use about 1/3/ seems to work better this way than using a vaccum line. let it sit a while and start her up and watch the smoke rip as you drive away. Just make sure you dont kill the engine by pouring it too fast and you'll be fine as long as you remember to put your intake back on

And...I've heard of making a 50% gas/50% SEAFOAM mixture to pour down the TB? Anyone else ever heard of doing this?

I pulled the vacuum line off the power booster & poured 1/2 can in slowly. I stuck a rag in the line & only unplugged it enough to let in a little bit at a time while it was running. Then let the white smoke roll.

You probably know this, but if you pull this line off without plugging it, the motor will rev up considerably.

After you do this would be a good time to change plugs as I fouled out 1 of mine doing this

Hope that helps.

Do you know what the master cylinder is? Its where the brake fluid goes.

Directly behind it (attached to it) is a large round object. It sits down a little bit lower. This is the power booster. There is only 1 hose coming out of it - that's the vacuum line. The other end of it runs into the throttle body. On mine, its on the upper LH side (as you're looking at it from under the hood).

There will be some kind of plastic plug looking thing (kind of like a big PCV valve) where the hose goes in the power booster. You just need to pull the plug out. I remove the clip & take off the plug when I do this - its just easier.

As I said before, make sure you stick a rag in the hose when you start the car or it'll rev up like crazy. Then, just pull the rag out a little bit as you pour the stuff in SLOWLY. Your rag will get a little wet, but, hey, its a rag.

I hope that helps.

I do the 1/3 process. 1/3 in the tank, 1/3 in the oil and 1/3 through the vacuum line on the intake.

I ma now a beleiver in this stuff, worked great. I eneded up just dumping 1/3 in the TB, 1/3 in the Crank case, and the rest in the gas tank. It worked well. It probably would have even worked better if I had used it in vacuum line lol. (which is what I will be doing next time)

yea, if you pour it down the tb (don't know about a vac hose as i dont do it that way,) the engine will die on you. just try pouring it real slow and that gives it more time to make it's way through everything, let it sit like 10 mins or what ever (off) and then start up and drive.
