I have a 2004 Pontiac grand am and I’ve been noticing the past couple days, when my car is off the temp and gas gauge move up literally like 2 minutes after I turn it off and take the key out of the ignition. When I put the key in the ignition they go back down, and they also act normal when the car is on and I’m driving but I can’t find anything online as to why they would do that while the car has no power. It doesn’t seem to be draining my battery but idk if it’s something I should worry about or not.
