Hay guys I just got a 2006 mini and I need your help figuring out whats wrong. So when I turn the car on for starters its hard to turn on. It just sits *clicks clicks clicks clicks* then fires up. That may be a battery problem but thats not the main thing. The main thing is when the car is turned on the rpm goes up then down then up then down. I dont really know why but if you guys have a solution then I would greatly appreciate it. Here is everything done to the car. I just traded for it. I am only 17 and know very little about cars so if you all could give me a helping hand It would be a big help. Ill also post pictures of the engine and all that.
