I popped a CEL earlier this week that turned out to be code P1518 (stuck open IMRC's) and began the usual liberal usage of SeafOam and CRC intake cleaner. After doing this a few times and achieving nothing, I decided to just reach my hand back there and twist them manually. Sure enough, it was stuck hard and came free. Don't be shy. Just torque it good with your fingers and work it back and forth.
After I did this, I erased the code and took the car out for a few good revs. Sure enough, no more codes. But it needed physical intervention.
I guess my first indication that I had that problem was that the exhaust coming from the left side pipe was distinctly different from the right side. The passenger side IMRC was the one that was stuck open.
