If I stomp the gas it will bog, then rev up. If I start pushing the pedal slowly it revs fine.
Do you

There or mainly three things that can make the engine bog under load, a clogged catalytic converter, and bad MAF sensor or a weak fuel pump. Here are guides to help you figure out which one is the problem and I have included instructions on the part replacement in the images below.

And a generic guide on how to replace the MAF sensor with the location it the images below.

Check out the images (below). Please let us know what you find. We are interested to see what it is.
