Carbed?
Broken distributor, cam jumped a tooth, valve spring broke, very lean, blocked exhaust.
Those are the first things that come to mind.

Re: something happened?
If it is an MAF TPI, it could be the MAF sensor. Though that would cause a nearly un-runable idling condition and would the make the car very difficult to drive period...assuming it even runs. This sounds like switched spark plug wires or timing is off.
