Intermittent shuddering when idling or at a stop. Replaced intake manifold, intake solenoid, PCV valve. Checked all hoses. Shuddering got better after replacing the parts listed, but the issue hasn't completely gone away, neither has the check engine light. Error code p0215

Is this a diesel engine?

P0215 - Engine Shutoff Solenoid Malfunction

If so, I would replace the fuel filter/water separator and then clear the codes. Please let us know what happens.

Okay, I have seen the fuel pump control module have an issue and cause this code and it will make the engine idle rough, please go over this guide as well:

The control module is at the top of the fuel tank under the fuel pump access port. Clear the codes once completed. Check out the images (below).
