No engine light on. We changed plugs, cold packs and mass air flow sensor. Any suggestions?

Can you confirm the car only has 16k on it? Have you tried down shifting the transmission manually? I would say you need to check the catalytic converter, but I have not seen this part go bad with that many miles on it. Here is a guide to go over as well to help see what can cause this problem:

Also, can you please check the air filter? Here is how in the images below. Check out the images (below). Let us know how it goes.
