Hi! Sorry if this is a dumb question, but I don’t know much about cars and haven’t been able to reach any mechanics because of my work hours. I am wondering if this is something I could postpone getting fixed until next week (my schedule right now is super busy unfortunately) or a "please get an Uber to work or you will die" situation. I was driving on the interstate and then my car started making this fluttering noise that sounded like when you go up a rollercoaster except if you went up them at 100mph lol. It only seemed to happen at above 40mph? or at least it wasn't noticeable when I dipped below that, and it stopped making noise altogether regardless of how fast 1 was going for the last 20 minutes of my ride home so I thought it fixed itself until I got out and saw... this. Thanks in advance for your help!
