Lately my car has been jumping rpms out of nowhere at idle. Some days it runs good some days it runs really funny like yesterday when i was at the stop light the car just went up to 2500 rpm on its own without me doing aynthing. Also the rpms been bouncing up and down a lot. I really dont know what the problem may be. Thanks for the input
