what may be the cause of the intake manifold exploding in my 2001 buick regal ls

What is your question?

We were trying to figure out why the engine kept idling higher after starting. We finally figured it was the throttle body sensor and the overheating was due to a bad water pump. After having the battery charged it wouldn't turn over. While getting a jump start the car suddenly let out a loud BOOM ! Assessed the situation and discovered that the intake manifold blew up !

What makes this problem better or worse?

while getting a jumpstart, after turning the key the intake manifold exploded. can you please tell me what can cause this to happen ?

How long has your 2001 Buick Regal had this problem?
