Shuttering when going up a hill or grade

Hi and thanks for using 2CarPros.com.

Have you checked fuel pump pressure? Also, have you checked to make sure the catalytic converter isn't plugged? Does the check engine light stay on or flash when this is happening?

Here are links that show how to check fuel pressure, a catalytic converter, and the third is a quick video on using a scanner. Check these things and let me know what you find.

Take care,
