I have a 2008 GT with C&L CAI and U7145 Diablosport Preditor tuner. I have the following trouble codes:
P2004 - Intake Manifold Control Stuck Open (Bank 1)
P2005 - Intake Manifold Control Stuck Open (Bank 2)

The trouble light will come on and then go off again in a day or so. I have also reset the trouble codes with my tuner but they return after a couple of days. What do these codes mean? Are they serious? Should I take to the dealership?

Thanks!

These codes appear when the CMRC plates are commanded closed but the monitor sees them as still open.

Possible problems
CMRC monitor signal circuit shorted to POWER/GROUND or SIGNAL/RETURN
Damaged CMRC actuator or solenoid
Blocked vacuum hoses

Thanks for the reply!!
Sounds like I need to tune back to factory, install factory intake and take to dealership. I only have 15K miles, so it will be covered under warranty.
I put 300 miles on her today before the same trouble appreared again. That should rule out a short/ ground right?
Cheers!
