Maintenance/Repairs

I have a 2009 Cobalt with the 2.2L engine. I replaced the camshaft actuator solenoid/variable valve timing solenoid (depending on what you would like to call it) on both the exhaust and intake sides of the camshafts due to a P0014 code. The engine oil is good (recently changed it personally) and I used the right verbosity. I immediately noticed the car started quicker/easier, ran smother than it ever has since I owned it, and idled smoothly. My daughter drove it town and the car made a noise (I can’t describe the barking sound she made for the noise) and the car ran rough and the check engine light came on as they pulled up to the store. She killed it, came outside, and the car ran fine and no more check engine light. The code was again the P0014. I checked the ohms on the exhaust solenoid and discovered it to be 25 ohms. I keep seeing on the interweb this should be between 8-12. Is this correct (the ohms range) and if so, I assume I got a bad solenoid?
