Check it again, check the secondary butterflies. There are two sets, the upper and then the lower. I had a butterfly cam move on me and it drove me nuts. It was holding the secondaries open slightly.

Also look for vacuum hoses which might have popped off. If a rocker broke or a spring got weak or a valve bent, it would pop as well.
