Im wondering if the cold weather here has something to do with it as well? I bought the car back in the spring, so this is my first winter with it. I may try to reach out to the p/o and see if he has had similar issues. I'm just hoping its nothing major or a sign of something more significant about to go out.
EDIT- while watching the boost gauge during this process, i notice that the needle moves slightly, could it be wg opening and closing? (noob question lol)
