Hello again I'm back with my 2009 journey. This time i'm lost with whats going on with it. It was working fine then the starter decided to not work anymore so I replaced it. Soon after that it started acting up with keeping the rpm staying up. When the car is in park and I press on the accelerator the rpm starts to go up but then after a few seconds it starts to slowly go down. Can anyone help with what might be wrong with it? Any help would be appreciated.
