1998 Olds. Aurora, 107,000 mls. My car idles at about 2500 rpm's when its started, it's really loud and recently I've heard light sqeeling. After it warms it's fine but somtimes the rpm gage goes all wacky, jumping around like it's not attached to anything at all and the service vehicle soon advisory pops up on the dash. How serious is it? Please help.
