Hey Guys, I own a 2016 Subaru Wrx and I am having a couple issues. First I wanted to know if its normal for the car to idle at 1800 during cold start. It will stay at 1800 but gradually go down to 700 rpm once its warmed up. Secondly I noticed on my gauge for the mpg that it continues to go down by .1 while idling. This happens during cold start and when doing a full drive cycle. I never really paid much attention but I wanted to know if this is normal. Recently Ive felt some minor shakes in my car but you can only notice during idle and its intermittent. Any help would be greatly appreciated! I will post a vid below to see if I can show you a bit better.
