This is most likely a dumb qustion. I was doing the sea foam test on my 87 4x4 2.9 yesterday. I used a can of spray in the intake to clean throttle body. then put 5.oz in the engine, it said 1.oz per quart of oil. Then i did the 3/4 can into the intake through the brake vacuum hose. But to my surprise when i pulled the hose off brake buster the engine rpms went up higher. I would think that big of vacuum leak the engine would try to die. It seams backwards to me.
