Could it be the air filter or something else?

Welcome to 2CarPros.

First, is the check engine light staying on when the engine is running? If it is, then the first thing you need to do is scan the computer. Here is a quick video that shows how it's done:

Next, power loss can be caused by a few things. Things such as low fuel pressure, a plugged catalytic converter and so on can cause this. I am going to provide a couple links to explain how to check those things.

Let me know if the light is on. I realize most people don't own a scanner, but often times a parts store will do it for free or even lend/rent you the scanner. The same with the fuel pressure, most times they will lend/rent the gauge to you.

Let me know what is happening.

Take care and Happy 4th.
