    2003 CTS 3.2 engine codes p0660c, p0153c, p0496c.. HELP!

    Looking for some help on these codes. Just had a new waterpump, valve covers and gaskets, throttle body cleaned and new intake gaskets put on. I am getting these codes on my car when i pull them up on my dtc. Also my heat does not blow warm at all in my car. The fans and everything work fine and it switches vents fine when i turn up or down. The a/c works great.

    p0660c. When i clear the codes this always stays on. Something about the intake manifold tuning valve.. No idea what to do for this one

    p0153c. Im assuming i just need to change the driver side before car 02 sensor

    p0496c. Purge valve solenoid? My car does do the thing where when i fill up its hard to start but other than that it runs good and starts good.

    The car does idle a little rough occasionally. Really not noticeable though. Other than that it seems to run fine. Any help would be great as i dont know if these could be related somehow. Thanks in advance
