I have a 2014 Chevy Cruze LT 1.4L. When I turn my Air Conditioning turned on while the car is in idle, I get this loud revving noise every 2 minutes and my foot isn’t even on the gas pedal. I have replaced the Spark Plugs and Ignition Coil. I also bought an Ancel AD 310 OBD Diagnosis Code Reader, and it’s not throwing any codes. From what I have read, it looks like I will need to replace the PCV Valve or the Fan. Any thoughts will be appreciated.
