Hello about 2 weeks ago I started my car in the morning and the idle was very rough, the car was shaking. I ended up driving another car that day, because of the shaking. I went home that night and started my car and the shaking had stopped. The car ran fine until 3 days ago, when I started it in the morning and the same thing happened. I let it run and sit for a while and pressed on the gas a few times and it went away. it's happened every morning(3) since. I smells like it's running rich while it's sitting there as well, but goes away after it starts running right. there are no check engine lights on and the temp gauge always is below medium. Car has around 96,000 miles and only seems to do it the first start in the morning. Anyone have any idea what the problem is? where should I start?
thank yall in advance
