There are three main reasons this can happen, first please check the air filter. If that looks okay let's test the primary catalytic converter. You can remove the primary oxygen sensor which should help.

here is a guide to help:

You also could have low fuel pressure but let's run the codes as well.

Check out the images (below). Please let us know what happens.
