Hello, my name is***** code you are getting is for he variable intake system. It means that the intake runner is sticking. If it happens more in cold weather it may be from carbon build up. If it is intermittent I typically recommend cleaning the intake system with a can of seafoam. This can be slowly added into the engine through a vacuum hose while the engine is running. Then the code should be reset to see if it comes back. if it does then the actuator may be failing. It can also be caused by a leaking vacuum hose but that is not as common if it is running fine. I hope this helps. Please let me know if you need more help.
