I can't figure out how I'm supposed to get seafoam into the brake booster vaccum line... if I let the engine warm to operating temp and let it idle, then disconnect the brake booster line at the booster, the engine dies instantly. How am I supposed to get it in there? Is there somewhere else I should pour in at on the 2.8?

 

Ahh, nevermind, got it. And just to help out future searches, here's what I did:

Place a clear hose(clear makes it easy to see) into the Seafoam can. Put the other end near the brake booster line, and loosen. Crack open just one edge and let the vaccum suck the liquid out. Follow instructions on can as normal. Careful, though, cause even when you close the line, the liquid will still continue to pour.
