I change the spark plugs, and put everything back like it was. But now its has a rough idle, rpm gauge is going crazy, and it will event shut off. I am thinking it is some type of leak. Just dont where or why is it leaking. Because I am sure put everything back the way it was. Just confused right about it.

What engine in this? V-6, and you had to pull the plenum? Possible you left a vacuum hose disconnected.

When its running, do you hear a hissing sound? There is a vacuum hose underneath the plenum that can be easily left disconnected.
