Okay, there is a technical service bulletin about this issue. A TSB means this is a common problem with the specific make/model but it is NOT paid for by the dealer. The issue lies with the camshaft actuator solenoid which has screens on it that can become damaged and missing. Replacing this solenoid should fix the issue.
