Never had this problem before, but as I was trying to accelerate it felt as if it was struggling to gain speed. It started sputtering and it felt as if I was almost to the floor with the pedal and nothing was happening. All of a sudden it just cleared up. I had the same problem with that again, and then a 3rd time. But after the 3rd time it stopped doing it. Haven't the problem since then. But my car is a 2001 and has a little over 46k miles on it.
It's usually a dirty MAF or you need to change your fuel filter.

That really has nothing to do with O2 sensors or a cracked manifold. The car runs fine with bad 02 sensors.

When it bucks or doesn't accelerate it has to do with the air/fuel mixture. Either it's not getting enough fuel (contamination in the fuel lines plugging the filter for a while) or the computer can't get the air/fuel mixture right, usually due to contamination of the MAF wires.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
