Hello, I noticed when starting the car after it had sat overnight in the garage or when starting the car after work (idle for 8 hours), the tachometer will rise to 1500 for 30+ seconds before falling back down to around 750. Please see attached video for example. I don't remember this always happening and thought it was the cold weather causing it to warm up but I noticed the revving issue still occuring even when it has been sitting out in 70 degree weather. The other cars I have does not do this and I also don't remember this being an issue when I first bought the car.
