Ok so my car has been doing this thing for a REALLY long time now, like 6 months off and on, where i'll just be crusing and i'll get power loss. It feels like fuel is being cut off to the motor. So i did some research and heard that i might need to clean my EGR ports so i went ahead and did that, however i still get the problem. When i unplugged my PCV valve it seemed to go away.... is it my PCV valve or something else?? I didn't have the PCV valve off for too long and thats why i'm asking
